Hi

We're experiencing problems with the new 64-bit Cygwin with Geomview (http://www.geomview.org). OpenGL doesn't appear to function. Piping communication from third-party applications fails - though both opengl and piping work fine in 32-bit Cygwin and on other 32- and 64-bit platforms.

Hints appreciated.

(Instructions for building Geomview and SaVi under 64-bit Geomview are at
http://sat-net.com/L.Wood/software/SaVi/building-under-Windows/ )

It would be helpful to indicate on www.cygwin.com that 64-bit is very new, and 32-bit can be regarded as stable...

thanks
