Hi vanRijn, I've confirmed that the issue happens regardless of whether I have the "Enable Mac OS Host Keyboard Shortcuts" checkbox checked or not. It does appear to happen less frequently with it checked, but I think that's just because when I press key combinations using the Command key that I end up accidentally switching away from VMWare because I'm used to that key doing something different.
In fact, the Control key got stuck on while I was writing this reply while pasting in the words "Enable Mac OS Host Keyboard Shortcuts" above.
