I've been running 136 for a couple of months with no problems. I downloaded
138 yesterday and used it for a while without problems as well. However, I
rebooted during the night, and now the PDE won't run any of my sketches.
I'm on 10.5.2. I did not install any new libraries. Exporting to
application and applet result in working sketches.

Error message:

i think this is related to bug #775, where things just poop out on the mac
sometimes... have you tried another restart?

another thing to try is to disable networking.. shut off airport if you're
using that, or unplug from the network otherwise. then see what happens.

this is sometimes a problem when the jvm is getting your ip address:
address=cincinnati118.ipcorporate.com:55422
and that ip is not in fact your machine, but some outside gateway machine.

Turning off networking did the trick. I just realized that the last time I
tried to run a Processing sketch, I was at home. I am now at work.

I hope you can find a way to work around this. Sometimes (e.g. right now) I
like to work on sketches over lunch, and I would hate to have to kill my
internet during that time.

yes of course, it's unacceptable to have to shut off networking... just a
workaround for now.

I am running 10.5.4 and 0142 and get the problem as well. But
unfortunately restarting and computer multiple times and unplugging the
network does not work. Any recommendations to get a work around so I can
at least start to actually learn the language. Thanks.

UPDATE: It currently works now. I unchecked max available memory.

ok, comment #7 and comment #8 refer to a different bug, which i'll need to
account for as well.

in the meantime, here are prerelease versions of 0143 that might fix the
problem:
http://processing.org/download/processing-0143p1.zip
http://processing.org/download/processing-0143p1.dmg
http://processing.org/download/processing-0143p1.tgz

please give one of these a try and see if it fixes the problem.

fixed for release 0143.
