I hadn't tried DA since one of the first betas, and certainly not since I installed Vista.
Today I decided that now that it is finished, I'd give it a shot. First thing right out of the box, during the splash screen, I notice the mouse "sticks" to the top of the screen. It continued to do this at the main menu, and I had to use Alt-F4 to exit the game since I couldn't even mouse down to "quit"...
When it does this, the mouse will move a little bit, then snap back to the top. The whole time, it is flickering back and forth between the Vista cursor and the DA cursor.
I'm not sure whatsup, but I certainly can't play the game like this.
My system:
Vista Premium
AMD Opteron 170 (dual core), 2gb Ram, 2.8ghz.
DFI LanParty UT NF4-Ultra D motheboard.
ATI x850xt PCIe video card, 256mb.
Logitech Cordless Optical mouse LX-5.
If any more info is needed, feel free to ask. Everything else works fine on this system.
