Running 0118 Build on Mac OS X.

1) Go to preferences and focus on "Editor font size:"
2) Change to any normal value (I tried to change to 12)
3) Press OK to accept changes, but the following is thrown in console:

i can't get this to reproduce, but it seems related to this problem:

http://processing.org/discourse/yabb_beta/YaBB.cgi?board=SoftwareBugs;action=display;num=1160057791

and for you i'd have the same question: is it possible that the "monaco"
font on your machine has either 1) become corrupt 2) gone missing or 3)
have an additional version installed that's causing a conflict?

is there any other software you might have installed that could be causing
th issue? what sort of machine are you running on? have you installed an
early access release of Java? (i.e. the developer preview of Java 1.6?)

also try setting your default java version for 1.4 instead of 1.5, and see
if you get the same problem.

i've looked into this further, it seems that something went corrupt in your
preferences file. the options that control the memory setting (the one
below the editor font size) seem to be missing. is it possible that
preferences.txt was edited in some way, or for instance if you had two
different versions of processing open at the same time?
