RE: Xfree and OpenGL

["Harold Hunt" <huntharo at msu dot edu>]

David,

Just as a sanity check, you have run non OpenGL applications from your SGI
machine using Cygwin/XFree86, right?  I mean, it wouldn't make much sense to
jump right into debugging complex applications if an xterm doesn't work
correctly.

Just let us know that you have in fact done this.

Harold
