Sorry guys, but anyone can tell me what seems to be the problem Im having? After installing properly Processing, theres a message saying:

Uncaught exception in main method:
Java.lang.NullPointerException

My console info says:

2006-10-05 16:24:35.932 JavaApplicationStub[252] Apple AWT - CGFontGetHMetrics returned NULL.

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?

the other problem here could be that the preferences file has gone corrupt. is it possible you had two different versions of processing open at the same time? or edited some of the file by hand to cause the error?

later confirmed this as what happens when you disable monaco:
http://dev.processing.org/bugs/show_bug.cgi?id=562
should anyone else run into the same error.

in a future release, i'll see about adding a warning message to this effect. (check the bug report for progress on such a msg or workaround)
