Problem with Blender 2.45 in the UI


I tried to update to the new Blender 2.45 today and recognized that it doesn`t display my working Project right at the moment.

I made two screenshots of the same model displaying in 2.44 and 2.45 on the same Mac
Dopes anyone else has the same Problem? How can I avoid this? I tried it on several Macs here, so it isn`t the System that has the Problem…

Greetings Mr.Gosh

So nobody else has problems with blender 2.45 opening old Projects?
