Working here too.
Installtion was fine
Except i also have the GUI mistakes.
And i have one other problem!
The LED for +2 on the ocatave selector, is always lit, not completely lit, but only half, and the light is not steady.
as i recall i have had this problem before in a 3.xxx beta??
I am not sure i recall it right though. otherwise i am looking forward to using the new features!
My system: win7 x64
P.S. i can also comfirm that the old known problem Win7 slow gui problem is still here.
