On 1): Did not check that, all my devices have standard resolutions above that. And putting your resolution below that, well, never even thought of that. Will look into that.
On 2): Yeah, it seems 3.11 is even more strict on turning off UAC... With previous versions I just put storage on a non-restricted folder and then enabled UAC, but with 3.11 it will not allow you to continue with UAC on, even though the Windows (Vista/7) VirtualStore methoud should get you around that...
