-Bug Fixes
*Fixed a bug where if you closed a game, then opened it again, you'd
get an error message saying that the maximize hotkey had already been registered.
(Not actually bad, but started to annoy the heck out of me ;P )
*Fixed a bug where trying to swap the hotkeys (or make both fields the same
set of hotkeys) when a game was active wouldn't work, and would cause invalid
hotkey entries.
*Fixed a bug where if the game was minimized through the 'Minimize if game
loses focus' checkbox, the active window would keep switching to the desktop every few
seconds. (Very very annoying stick out tongue )
*Fixed an error where if the DSM was used in conjunction with the 'Minimize if game
loses focus' checkbox, the resolution wouldn't change.
*Fixed a small glitch where there was a delay in the hotkeys working if new
ones were set while a game was active.
*Fixed a few loose odds and ends around the menus and added a few more error checking
functions.
