*This applies to PhotoModeler Pro 4.0 only. PhotoModeler Pro 4.0’s 3D Viewer uses Microsoft’s 3D interface called Direct3D. Many computers have built in hardware acceleration for Direct3D. The problems is due to a bug in Direct3D and its interaction with the hardware acceleration. This problem usually occurs on Windows 2000 systems only. To solve the problem try turning off hardware acceleration (which means Direct3D still works but may be slower).
To turn off Hardware acceleration:
The status should now indicate “Disabled”. If the dxdiag.exe program cannot be found on your system you may have an older version of DirectX installed (note you cannot upgrade DirectX on NT 4.0). In this case please try the instructions below for reducing general video acceleration.
