So I took the plunge and installed SP2...
 

...and so far the only fucked up thing I've noticed is that I can no longer play .asx video files.

Before SP2, .asx = yes

After SP2, .asx = no

But that's ok, because I don't give a shit about .asx anyway.

I would try SP2 out, but I think someone mentioned that it doesn't play well with CuteFTP, and I have that installed on both my machines.

i have sp2 installed and run cuteftp... no probs for me at all...
