Changing DirectDraw® support

AVWorks supports DirectDraw, a standard that allows direct manipulation of video display memory, hardware blitting, hardware overlays and page flipping without the intervention of the Graphical Device Interface (GDI). This can result in smoother animation and improvement in the performance of display- intensive software.

However, if your machine has a software cursor or pointer shadow enabled, or if your video driver does not support DirectDraw, you may experience a flicker in your mouse cursor when over the title bar of the Viewer.

You can either disable the software cursor or pointer shadow, load a new driver for your video card or disable DirectDraw.
