Alan Isaac My guess is that the default rc file is using GTKAgg -- I usually reset this to TkAgg for the windows distro, and manually set Numeric for the numerix setting. In this release the rc file is autogenerated depending on what was found at build time. Quick fix: just set TkAgg (or whatever) in your rc manually. Charlie: make a mental note on the bug-fix build to automatically set the right defaults in setup.py for win32 builds. JDH
