On 32-bit Cygwin, SaVi talks to Geomview, you get a view of the Earth with a ring around it when you launch the two, you can control Geomview with SaVi and its menus as expected. On 64-bit, Geomview launched with SaVi: >> geomview -run ../savi1.4.9/savi >> gives a blank grey canvas window. Though SaVi may be listed as a module in Geomview's main window, clicking that does nothing. There is no piping communication between the applications. At all. may be is a piping problem, but there is no evidence; it could be a lot of different issues due to 64bit porting. I will not be surprise if there is wrong assumption on data size. >> Geomview is available from http://www.geomview.org/ > SaVi is available from http://savi.sourceforge.net/ >> regards >> Lloyd Wood > http://savi.sf.net Regards Marco -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
