Hi,
I just installed 1.01 and experienced 2 issues:

1) r4 visualisation is starting on every configuration start, and also if MP is started in windowed mode.
2) The first start of MP takes AGES... It took about 5 minutes- the second start however is as fast as usual.

what can I supply to give more info? Or are those two things already known?

cheers

Update:
FYI: the startscreen is usually hanging at "Initialize Texture Manager"
