First of all, there have been others who asked the same question but none of them have recieved working answers.
I've been using RDP from school on Windows 7 for a while, and I recently decided to make the jump to Windows 8. There's not a whole lot of problems, but many of the times I close RDP connections from the school computers (which run Windows 7) my home computer is left with a black screen with a cursor on it. When I RDP back into the computer, it disconnects after around 30 seconds. If I physically access the computer from home after this there is a black screen on my primary monitor which disappears if I click anywhere on my secondary monitor. I'm not sure what's going on here, but I really need to get this problem fixed for my programming class.
