Hello everyone!

I got a problem, hope one of you guys can help me out...

I don't know if I have changed any settings or something (I was just checking out the Hypergraph mode), but all of a sudden I can't use the tool list. Nothing happens when I click on any tool. I've restarted the program but the problem is still there.
The "quick menu" which should appear when you rightclick on an object is also gone. Nothing happens.

Does anybody know what I did wrong?

Cheers/
Marie
