OpenGL DLL
From ATTWiki
Some systems have OpenGL implementations that have bugs that cause serious problems with our graphics-based software. In most cases, dropping this OpenGL32 DLL file into the same folder as our executable will solve the problem. Other versions of the DLL may work fine - but we've prove this one and know it works.
- Download the zip file that contains the OpenGL32.DLL file.
- Unzip the file.
- Close the program that is experiencing problems if it is running.
- Copy the DLL to the program folder.
- Start the program.
