Flash CS4 crashes on OSX – could be a font related problem

Font Book on OSX

I spent some time this morning guessing why my .fla file (created in CS3) constantly crashes my version of CS4 in Snow Leopard. After the 10th crash (and repairing permissions and deleting preferences), I had a closer look at the crash report. It said something about com.apple.main-thread and some vaguely font related things…

Now I’m not an expert in crash reports but I had a look in my font list (using Font Book – which can be found in the Applications folder) and there were a few issues (duplicate entries and one or two corrupt font files). After fixing those issues by removing duplicates and deactivating corrupt files, I could start Flash, edit the file and publish it as usual.

Hopefully someone with similar problems will find this helpful.

I've always been interested in all kinds of art because I felt the need to express myself in many different ways. I paint, draw, create 3D models, motion graphics & designs of all sorts, play guitar, love photography and whatever else is in between... I was born in Hungary and lived in Hungary, Germany, Australia and the UK for a number of years. I speak German, English and a little Hungarian (I'm working on improving that one again!).
