what's your login name on windows? looks like it contains something weird, though i'm confused because the whole point of the changes for 91 was to fix this sort of thing.

bummer.. Léo shouldn't be "weird", i wonder if the fixes for some names with ascii characters perhaps broke it for others.

what language is your version of windows? i wonder if english versions of windows (where i debug) are treating this differently.

I use XP home edition in Korean.
I have similar problem and can't run 91.
Although the error message says
"
C:/Download/Processing/Processing/processing-0091/..java:0:0:0:0: Semantic Error: The input file "C:/DOCUME~1/??????/LOCALS~1/Temp/build/Temporary_9422_2161.java" was not found.
"
the java file:Temporary_9422_2161.java does exit in that directory.

Since 69 did not have the problem, I realized that it is the Korean characters used in directory names.
In 69 the temporary Java files are created in ..\lib\build\ under the lib directory.

In new 91 version they are moved to
**\Documents and Settings\소유주\Local Settings\Temp\Build\.
The directory name just below **\Documents and Settings is the directory name in Korean which means "owner". This is is the system directory whose name I can not change at my will.

hm, i've just tried both Léo and 소유주 and both work fine on my machine. i wonder what the difference is?

are you both using xp home? are you using service pack 2? i need to figure out how to make it break so that i can debug it

I am using standard version ,Java included.
My XP home edition is with SP2.
I have another PC with XP professional installed and in that machine 91 runs fine. In that machine the user name is in English and the directory name where temproray Java files are created are all ASCII characters.

Anohter problem with the 91 is that sketchbook dirctory is being built when you first run 91 and the directory is some funny characters, neither English nor Korean and can not recognize next time. Every time when your launch 91, 91 asks to create a new directory for sketchbook.
This problem is fixed by modifying preferences.txt file
*****
sketchbook.path=C:\Documents and Settings\proc\My Documents\Processing
******
and changing strange charactered dirctory name to "proc" by hand.

It is surely non-ascii user name causing compliler error.
In XP Pro version, I created user name with Korean characters and the complier cannot recognize the build directory.

On the other hand when I create user name in ASCII code in my XP home machine, rev 91 runs OK with a minor problem. It does not start from processing directly but only from "run.bat", possibly because default paths are not correctly set.

As to the rev 90, I dowloaded on XP pro machine and in Korean user name, I get similar compiler error messages:

Compiler error, please submit this code to http://processing.org/bugs/
