LWUIT + Nokia SDK 2.0 Form turning black, when swiped on screen

Question

I'm having a strange problem with the Form of LWUIT. I am making a simple game, which you can control with the touchscreen. I just want to use simple touch events, no swipes. However, when a swipe event happens, the screen turns fully black. After some normal touch events, the picture comes back, but this is really annoying. Which property of the Form do I have to set, that this doesn't happen? The problem does also occur on the phone itself, not only on the emulator.

Answer 1

Solution: I had to override the public void pointerDragged(int x, int y) method inside my form (empty body).
