Why does the Simulator screen appear black?
When you first launch the Widget Development Simulator, the screen may appear totally black. Resizing the window (maximizing it and returning it to its regular size) forces a refresh of the background and provides the correct display. This workaround is also valuable when playing video. Pressing the F10 key (BACK) causes video playback to stop, but does not close the video screen. Resizing the window after pressing the F10 key (BACK), forces a refresh of the background and provides the correct display.
