Hi, sorry if this isn't the right section for this, but I'm not sure how to classify this issue.
I installed Mint 15 64-bit Mate edition on my Asus G73SW beside my existing Windows 8 system the other day. The installation went smoothly but after booting into Mint, I've found that sometimes I can only use the arrow keys to navigate a dialogue box (as clicking does nothing, as if the window were not selected as the "working" window). When I use alt+tab I can cycle through which window is on top, but still cannot interact with the window being shown. I have found that sometimes making clicks on a window registers on the window beneath it instead, for some reason.
This problem seems rather odd to me; I have never experienced anything like it. I tried booting a few different Live Linux distros (Fedora, Crunchbang, openSUSE) and have confirmed that this problem happens in all of those environments as well. It does not occur in Windows, though.
Can anyone shed any light on what's happening here?
