It’s very important to have the latest display drivers for your video card installed. Display drivers can be downloaded from the web site of your video cards manufacturer. If you don’t know which video card you have, click here.

If the problems continue, try the following:

1. Change your Colour display to 16 bit. In windows, right click on your Desktop, and select Properties from the menu. Click on the Settings Tab and change the display to 16 bit if it was previously set at 32 bit.

2. Use half-size textures to save video memory. Select File-Preferences-OpenGL. Check the "Use half size texture" box.

3. Screen Resolution. If your screen resolution is set at 1400 pixels or higher, switch back to a lower resolution.

4. Close down other programs to save on memory resources. Look at your system tray (bottom right where the time is displayed), if you have a large number of applications running, this will affect performance. Right clicking on most of the items listed in the system tray will allow you to turn them off.

5. Keep your operating system up to date by doing a Windows update. Click the Start Button-Windows Update. This will download the latest patches to make your computer run smoothly with your applications. Consider also updating Internet Explorer to the latest version.

6. QuickTime. Starry Night 6 requires QuickTime 6.5 or later, which is available on the CD. Open the sample.mov file included in the installation (inside the QuickTime folder on your local hard disc) and see if this movie plays. If it doesn't, you might have to reinstall QuickTime.

7. Also try the following. Right click on your Desktop and select Properties from the menu that comes up. Then click on the Settings tab and click on the Advanced button. Click on the Troubleshooting tab and move the hardware acceleration tab a couple of ticks to the left.
