About PATCHOGL PATCHOGL may be used to patch OPENGL32.DLL versions shipped with Windows 9x. Just start PATCHOGL with the version of OPENGL32.DLL to be patched in the same directory. A patched version with file name OPENGL32.NEW will be written if the pattern has been found. What does the Patch? The unpatched version of OPENGL32 uses an OS-dependant way to access thread local storage (TLS), which may cause problems with HX. The patched version uses an OS-independant method to access TLS and it is safe to use with HX. And it still works with Windows. Japheth
