Java Development Tools

I know that it is rather hard to get a keyEvent for the soft keys but they are behaving VERY weirdly and I was thinking it could be fixed by running some code when they are clicked?

Basically the game involves sprites that move around at a set speed which doesn't change. However when the menu is brought up, the game looks as though it pauses (nothing moves) but it I then close the menu, it is apparent it hasn't actually paused as the enemies have moved around. The key issue however is that the speed is increased dramatically. And every time the menu is opened they speed up. If I open a new canvas from the menu, and return then they go back to normal speed. What is going on?

Thanks
