ohhh Apple, so fickle.

will look into it, but in the meantime, try renaming/deleting your
preferences.txt file and see if that doesn't fix things at least for the
time being.

renamed pref file, no joy. :(

what method are you using to open the sketch? cmd-O, the menu, the toolbar,
double-clicking from the finder?

File > Sketchbook -- crash
Cmd-O; sketch loads, runs, with console message:

yeah, i'm getting error spew with file > sketchbook > ... but it's still
loading and working. will have to look into it further.

I'm getting error spew as well and overall Processing seems to be running more slowly.
Shortcuts are not working reliably as well, such as Apple + N to open a new window.

I'm not sure if this is part of Processing 1.1, but when I open a new example sketch or attempt
to open a sketch in my sketchbook it wants to close the one I am currently working on, while
previously it opened a new window.

I'm going to be teaching with Processing starting next Tuesday so it would be great to have this
error disappear, even if whatever is causing it does not get fixed right away.

There's not much we can do about Apple's bugs except try to find
workarounds. There's nothing we can do from a Java application to cause an
assertion failure in Apple's code--that's something happening at a much
deeper level than what we can do from Java. The only thing we can do is
hide the error, but I'd rather that Apple fix this garbage.

As for opening new sketches, this is covered in the reference (Help ->
Environment).
