Turns out it does make a difference. This documentation page:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms646309%28v=vs.85%29.aspx
explicitly says that the behavior of the underlying API has changed
since XP: if the hot key is already registered, the API now fails
instead of replacing the old registration with the new. And Alt+TAB
is hooked by the Windows Explorer. And indeed, on Windows 7 I see
that the call to RegisterHotKey API consistently fails with an error
code which says "Hot key is already registered".
Unless someone knows a way around this (I searched for it, but didn't
find any solutions, only complaints), I guess this will remain a
"known bug".
Does this work for you with other key combinations, btw?
