[Gmsh] problem with graphics window (Windows version)

[Larry McMichael]

After downloading and unzipping the Windows binary file for version 1.43.0 
under Windows 2000, I launched the gmsh.exe executable. The graphics window 
and command window both appear, however, the graphics window contains a 
partial image of the current desktop display (i.e. open windows and the 
background image). Opening one of the tutorials or demos does not clear the 
graphics window. I tried changing the color scheme used under 
Tools->Options->Colors, but there was no change to the graphics window. The 
OpenGL, glu32, and cygwin1 DLLs are installed and found in the path 
variable; there is only one version of the cygwin1.dll. Any help 
determining what settings need to be changed would be appreciated greatly.
Thank you, -Larry
