hotkeys problem

[mihai]

Hello,

I have a problem with my hotkeys: I set "space" as a hotkey and when I start stackandtile I can`t use it anywhere else(skype, websites). I know a message is supposed to appear telling you if you want to block the hotkeys or something like that. I tried deleting and setting back the hotkeys and is still the same.
What can I do?

Thank you!
