[fixed] Shortcuts stop working when Tweak is enabled and other bugs.

[Nova]

I have some reproducable bugs, where keyboard shortcut commands will execute instantly if tweak is enabled and some other bugs that appear as a result of it.

1) Enable tweak
2) Make cube
3) Move verticies around randomly using a keyboard shortcut (I have Shift + F bound to move > free) and this is where it's a little random because you have to be quickly selecting > moving > deselecting over and over. Eventually, without fail for me, the keyboard shortcut for moving will stop working. Other keyboard shortcuts still work. It appears as if the command (Move > Free in this case) is executed instantly, because the selection and the help bar flashes when it's locking up. If I instead hold down the keyboard shortcut, I can see the help text for Move > Free and moving is now very very laggy.

4a) If however, I focus on another app like a browser and then come back to Wings, ALL keyboard shortcuts will have stopped working. Space for deselect, the selection mode shortcuts (F for Face, V for Vertex, etc.), custom ones, all of them.

4b) If I disable tweak when the keyboard shortcut locks up, the keyboard shortcut starts working fine again, but any operation I do afterwards, for example deleting a vertex, is done twice.

Hope this makes sense.
