[FMX]Help! Unknown hotkey causing trouble!

Thanks for reading this! I need help fast!

Me and a friend of mine have programmed a hack & slash RPG in Flash MX 7.0. It’s built like this: Each frame contains a map, and when the hero character tries to leave the border, the map changes to a new map. So each frame has the simple “Stop();” command. (Like Zelda scrolling) This works fine, and when i’m publishing the .fla file in Flash and test it there, there is no problems.

But! When I run the published .swf file stand-alone with only flash player, this problem comes up: When I press shift-ctrl and up-right, the timeline jumps to the next frame! The same happens when I press shift-ctrl and up-left, but now it’s jumping backwards in the timeline.

This is a problem, because in the game shift, ctrl and the arrow keys are used very often together.

Teleporting through the maps are only avaiable to mages! So I have to disable this very strange hotkey. Do you know how?
