Any application that uses Alt+A for any kind of command will no longer accept the command. For example if I play Call of Duty United Offensive (yes I know it's old) and press Alt+A to sprint and move left it will not work. HOWEVER if I press A+Alt it will work.
I don't know when exactly this started happening, my guess is within the past 3 weeks. I've tried multiple keyboards and the same thing happens. I even went the route of looking for malware. Nothing I seem to do fixes the issue.
The odd thing is when I try Alt+A with an Autohotkey script it will NOT work, but if I have Computer Management open and I press Alt+A it opens the "Action" context menu. I am absolutely bewildered as to how to fix this. I have re-installed AutoHotKey and Call of Duty UO, etc. and this certainly did not fix the issue.
I'm running Windows 8 Pro 64-bit.
