Problems with mouse stutter and disappearing only occur if Windows is set to "Projector only"/"Second screen only".

Unfortunately that doesn't work well in my setup, as I don't have the laptop screen visible when I'm using the big monitor.

And... To top it off, after updating to 7.5 M2 and trying it here in the office with DVI display connected, I can't use "Second screen only"/"Notebook off", then I just get a black screen on both displays. Extend screen, works.

Really really limiting my productivity. Wish there was some way to prevent it from auto updating, until this is fixed, so I can continue to run the old 7.4 M2 which works flawlessly.
