Just a little warning to everybody from countries that have umlauts in their languages:
I tried to open up a bunch of old files but kept getting an error message. Obviously I thought it was a compability-problem between the versions (since I haven’t been very active with blender since the alpha came out), but about half a day later i managed to figure out that the culprit was the letter “ö” in the folder where the files was stored.
So, stay off those åäöıü’s!
Edit:
Oh, and I run OSX 10.5.8
