i figured i'd put this here instead of in the forums, hope i was right to.
i have just downloaded processing and when i try to run the program, it
just quits. here is what i get in my console (which i have no idea how to
decipher):

[LaunchRunner Error] processing.app.Base.main(String[]) threw an exception:

i have downloaded the most recent version of processing (as of today) ..
and am running on a imac with osx 10.4.7

thanks!

that looks like your installation is bad. possible causes would be 1) you
didn't copy processing to the applications folder and are running it from
the dmg file 2) you're using a pre-release version of java on your mac 3)
something else i can't think of offhand...
