I'm just wondering if there's a setting/key combo that can stop the program while it's running/executing simulated keys? Currently if there's an error while running I feel like I have to wrestle with the program to regain control!

You should be able to disable XMBC (e.g. using the scroll lock key or setup a hotkey to disable/enable XMBC), that should interrupt simulated keys (although I'm not 100% sure it will, and there may be a small chance a key may get "stuck" down) I would have to test that and make sure it behaves as expected.

You can use {FLUSH} simkey command in another button press macro.
Perhaps I should add a new hotkey that will do exactly this - stop the currently executing simkey sequence as gracefully as possible, but that will (obviously) require a change to XMBC. I'll add this to the list, but I cant give any estimate as to when it may get done - I hope I will get a little time to spend on XMBC between Christmas and the new year, but I cant promise!

As always you're amazing Phil, thanks for the response and I'll keep my eye on the horizon to see if it becomes a feature in a future update Happy Christmas to you and yours!

FYI, The next beta (2.21 Beta 28) will have a new global hotkey to abort any running simulated keystrokes.
It will be available here shortly

I keep my X-MBC [along with other such programs when run] visible in the Tray notification area. Sometimes I am able to close them executing Exit from their icons

Maybe such abortion command could / should be automatically executed whenever user physically releases all mouse buttons- so that X-MBC would never get stuck

That would be a sure way to break many functions in XMBC lol!
What about simkeys that are expected to take longer to run that the button is held
Or sticky simulated keys/actions
Or repeating simulated keys
And all the other cases that would completely break if everything was reset when all buttons were released!
