My bug about -2147483648 is more old, is 3099 and is set as "Done" 
also if it is not done or it is done in the wrong way.

that a bug from the rebol-view altme tracker... i guess it was misunderstood.

Yes, I think #3099 was misunderstood, and this is the report that 
agrees most with me. It should be changed from "Done" to "Issue"/"Bug".

who's car will I have to wash to get a RAMBO account? :-)

Do you want to submit a bug ? I'm pretty sure you don't need an account 
to do that (although it *looks* like you do).

couple of obvious and annoying ones in makedoc2.r. ahh... seems like 
I can

You should usually search the rambo database to see if it hasn't 
been submitted already, and also check here before submitting, unless 
you are really pressed for time.

I have problems with draw block in betas > 1.2.48:

draw [pen none box 0x0 100x20 pen 0.0.0 text 2x2 "hi!" pen none box 
0x21 100x40]

second box border isn't transparent. It seems that drawing text with 
a non-invisible pen override any future invisible pen color setting.

Version > 1.2.48
 does it mean "version upper than 1.2.48" ?
It mean AGG inside so!! It's alpha, with many bugs arround.

Try with a tupple of 4 value with max alpha value :
pen 0.0.0.255

yes, upper than

4 values color tupples don't works with official version

Yes, but should work with AGG ones

I use a workaround, putting all text display last in draw block

Q: what result does "pen none" give ? Transparent color, or no drawing 
!

it does draw, with black color in this case

For the first box or the second ?

only the second

And the first ?

the first is transparent

'text seem to affect pen selection: if I change 'text location, it's 
after 'text this problem happens

('text location in draw block)

I tried to make a face with text and invisible boxes

the boxes colors are changed at runtime

it's a draw version of 'textlist

s1: make struct! [] none
s2: make struct! [] none
same? s1 s2
;== none  ; (expected false)
same? s1 s1
;== none  ; (expected true)
blk: reduce [s1]
;== [make struct! [] []]
find blk s2
;== [make struct! [] []]  ; (expected none)
equal? s1 s2

;== none  ; (are struct! comparable like string! (expect true) or 
incomparable like object!  (expect false) ?)

Doesn't look like this bug is in rambo database. I should submit 
a bug. Any complaints?

Here's a more difficult one - FORM.
I always guessed that PRINT uses FORM internally:

print ["" "hello"]
;hello
print [" " "hello"]
;  hello    ; <--- 2 leading spaces
form ["" "hello"]
;== "hello"
form [" " "hello"]
;== "  hello"  ; <--- 2 leading spaces

Isn't that kind of inconsistant ? You have a choice of 0 or 2+.  
How do you get just 1 leading space ?
Furthermore:

prin ["" "hello" ""] print "."
;hello .   ; <---- 1 traling space
form ["" "hello" ""]
;== "hello "   ; <--- 1 trailing space

print rejoin [" " "whatever" " "] ;   ;)

The inconsistency is also between empty strings which are in first 
position or a later position in the block.

Yes, Izkata, I am well aware of that workaround.

No real argument from me, though, since I don't know and have never 
used 'form or simply printed blocks

However, I keep bumping into this problem and so it wastes my time 
continually. I also imagine it's a small confusion for beginners.

So, I would like:
print ["" "hello"]
; hello  ; <---- 1 leading space
form ["" "hello"]
;== " hello"  ; <--- 1 leading space
form ["" "hello" ""]
;== " hello "  ; <--- 1 leading and 1 trailing space
And similar results for PRINT.
Anyone have any objections ?

Anton - how can you produce space without actually providing a space? 
;-) "" is empty string. Even 'empty? tells you so ... it can't add 
space by some magis, just only because it is used in a  block or 
form ...

FORM puts a space between all items in the block when it is joining 
them together, even items which are empty strings - *except* if it 
is the first item.

You should read my examples more carefully.

Well now, that is not always true either !
form [{} {} {} {} {}] ; a whole bunch of empty strings
;== ""  ; <--- empty string
form [{} {a} {} {} {}] ; one character added
;== "a   "  ; <--- three trailing spaces

Perhaps form is just waiting until there's a value before it adds 
stuff?
>> form [{} {} {} {Hi} {} {}]
== "Hi  " ;2 spaces, and only after string w/value found
>> form [{} {} {} {Hi} {} {} {Hi} {}]
== "Hi   Hi " ;2 spaces and 1 space..


But yes, there probably ought to be a space in fron like you said 
before.  If the behavoir I think is happening, then 'trim should 
just be used, not letting it be automatic

I am guessing the logic behind FORM is that it changes mode at the 
first non-empty string.

Basically what I tried to say but couldn't type correctly  ;)

Anton - it does not matter imo. It is design of 'form or 'print, 
that those add spaces between chars, but once you put empty string 
into block, it is value, and the value is empty string, so it is 
imo incorrect to want it represent space

Read my comment above.

Pekr, look at this example. There are five items in the block (some 
are empty strings). So I expect five items to be separated by four 
spaces. 
form ["" 1 "" 2 ""] 

;== "1  2 "     ; <<<< but I count only three spaces in the result

Gabriele, I see #3455 and #3576 are basically identical. I think 
#3576 is more accurate, so older #3455 should be removed.

Ok, submitted a report for the struct! comparison bugs above.

Undecided about FORM....

Here's another bug:

BUG: using DETECT (instead of ENGAGE) is unreliable with stopping 
time events, as in this example:

lay: layout [btn "start" [lay/rate: 1 show lay] btn "stop" [lay/rate: 
none show lay]] lay/feel: make lay/feel [detect: func [face event][if 
event/type = 'time [print ['tick now/precise lay/rate]] event]] view 
lay
