Hello, I am testing processing on windows XP sp2 czech version. Localized versions of windows use translated folder names for system folders, so, in my case, C:\Documents and Settings\tk\Application Data\Processing\build becomes C:\Documents and Settings\tk\Data aplikací (note the non-english letter here) \Processing\build.
When the processing tries to compile any program, it seeks for some preferences in this folder, but the non-standard letters get changed into invalid character '?' (probably because the 'í' character doesn't exist in java's codepage). So processing tries to reach a folder with invalid character in the path, and returns only a set of errors:


Error: The directory specified in the "-d" option, "C:\Documents and Settings\tk\Data aplikac?\Processing\build", is either invalid or it could not be expanded.

I don't know which data are stored there, but since this can be problem of many non-english people, i suggest user-adjustable path to settings, not fixed place in 'Document and settings' folder.
Thanks for a wonderful programming environment, you have even made me buy a webcam ). Good luck with the further development...

this is the top item under "processing won't start" in the faq:
http://processing.org/faq/bugs.html#wontstart

looking into it. the paths should be user adjustable but because of a bug they're not working properly.

should be fixed for rev 91, keep your fingers crossed...
