A bit surprising though is:

>> true? all []
== true

At least it conforms to it's description saying "Shortcut AND. Evaluates 
and returns at the first FALSE or NONE." There was no first none 
or false.

double colors in 'draw dilect does crsh view... Is that known?

Without the use of line-pattern..

effect: [ draw [ 
			pen gray silver
			line-width 15
			line-join round        
			line 22x220 150x350
	 ] ]

I confirm on WinXP.

So am I.

discovered it last week... I imagined it was a known bug... but I 
didn't check  ':-/

It's in RAMBO #4040 http://www.rebol.net/cgi-bin/rambo.r?id=4040&

Cyphre said it's fixed, but not release yet (if I understand correctly)

Yes, I think I reported that bug to Cyphre during work on Compo demo. 
I hope there will be upgrade to View to fix this and other bugs, 
but I'm afraid that with R3 behind the door (you now, in just couple 
of days we're going to see the roadmap ;-), bugfixes for current 
View will be late.

:-) so we've got more couples of days, so what :-)

but look, I am not sure - Carl told us that submissions for 1.3.3 
should be submitted by us .... why Rebol 3.0 should prevent new View 
release, if bugs are already fixed? It is worth release then, even 
if no new additional functionality is released (as rich-text etc.)

Just noticed daylight savings ended. Windows changed the timezone 
from +11:00 to +10:00, but rebol still reports

RAMBO #3650 "crc32 function added to checksum" - I have just contributed 
a crc32 function to the rebol library. It's quite slow, but the rebcode 
version is fast enough. CRC-32 is still used by common tools (archivers...), 
and an implementation in the 'checksum native would be useful.

Do all these crc functions require the whole file to be read into 
memory?

Yes - both the native 'checksum and the published 'crc-32 works on 
a string! or a binary!, not a port! . For crc-32, the crc must be 
initialized at start, and complement'ed (bitwise 'not) at end.

- I have an internal function in crc32.r who allows working with 
big files and stream, but it isn't fully documented.

does it work though ?  :)

well, I hope so - it's the fundamental brick ;) but it's not intuitive, 
usage exemple (depends of port access mode...): 

crc: -1 while [not empty? data] [ctx-crc-32/update-crc data crc data: 
copy/part source length] crc: crc xor -1

so, it has minimal memory use with gigabyte size files?

crc-32.r with gigabytes files: [don't do it] - it works, the memory 
used isn't size relative - but on a 1GHz PIII, the speed is < 300 
kbytes/s! 
rebcode version is a lot faster (>2Mbytes/s), but 
1) rebcode isn't part of official releases 
2) the rebcode version of 'crc-32 needs whole file in memory.

so, back to RAMBO: #3650 - I vote for 'crc32 as another 'checksum/method, 

and maybe a RAMBO ticket for a port aware version of 'checksum would 
be a good idea.

I think this is a bug:

I understand, thanks. Anyway, I submited it into Rambo.

Ahh.. of course you do! (I thought it was strange me helping Oldes.)

encode the % as %25

ie. use http://www.paseka.cz/obalky%255C80-7185-652-5.jpg

what about this?

read to-url "http://www.paseka.cz/obalky%5C80-7185-652-5.jpg"

or more correct in this case:

sorry, this is correct:

I am having a serious problem:

    parse [*] ['*] ; == true

but

>> parse [/] ['/]
** Syntax Error: Invalid word-lit -- '
** Near: (line 1) parse [/] ['/]


The same problem exists for '// . Is there a way how to circumvent 
it?

I'm afraid there isn't. This is same as the "comma bug"

>> parse [.]['.]
== true
>> parse [,][',]
** Syntax Error: Invalid word -- ,
** Near: (line 1) parse [,][',]

it seems 'parse needs some overhaul?

this is the way: parse [/] [set w word! (nx: unless w = first [/] 
[[end skip]]) nx]

the same way can be used for [.]

(but is is not very elegant, I admit)

hmm, the situation with comma *can* be handled this way too, but 
comma normally isn't a REBOL word

yet another word of this kind: '<>

and '<

and '>=

another "problem":

>> first [<]
** Syntax Error: Invalid tag -- <
** Near: (line 1) first [<]
>> first [< ]
== <

I reported that the interpreter doesn't accept get-wrods startting 
with < (#3641)
