Hi there,

First, two notes:

As you stated, the program is old. Current version is V21. The issue that you described was very common at the time. Current versions include a control to manage this problem. The solution below is what we used at the time and it worked.


Yes, I moved your post.


This issue can be related with the fact that your program is rather old => old programs don't work well with more updated components (hardware) or with integrated video cards..
Try these resources:

- Check the website of your video card manufacturer and update the drivers.
- Go to the video setup on your PC (may be different for different versions of Windows and video cards); for most, click on an empty part of the windows Desktop, click on Settings => Advanced => Troubleshoot. Back the accelerations slider, one level each time and see if the problem disappears.
- Right click on the wallpaper (look for a place without icons) => Properties => Settings => Advanced => Open GL => Compatibility Settings => Force 16 bits => Apply => OK
- Set your video color depth at 24 or 32 bits ("true color").
- Go to www.microsoft.com/directx, and see what version is current and check if you have this version installed in your computer.
- Some NVidia card users reported additional problems => in this case change the color settings from 32 bit to 16 bit.
Now, if the accelerations controls are not available, this means that you don't have a dedicated memory for video. In this case, go to the control panel of your video chip / adapter => performance => move the control and set down the performance.

Hope this helps.
