[strage problem] Really strange

So as you know im working on first person shooter game.
But i encountered a weird problem, i implemented 2 buttons for weapons switch like “c” for first weapon and “v” for second weapon.
All worked well i exported the movie to desktop and was working just fine.
Then i sent it to my friend to see it and he was telling me that he couldnt switch the weapons.
I tought he was doing something wrong but then i converted the SWF file to EXE.
When i play the game in EXE i cant switch the weapons aswell, the buttons wont work.
Why’s that? in SWF on my browsers works jsut fine, but on my friends browser or in EXE wont work…?
