The 'freeview' app, now distributed with freesurfer, is built on WxWidgets. Once enough functionality found in tkmedit, tksurfer and tkregister is built into freeview, then freeview will replace those apps. Getting the internal momentum to do this will take some time, because tksurfer, tkmedit and tkregister have 15 years of functionality incorporated into them.

Are there any plans to migrate from TK to QT or WXWidgets?

Thanks for the pointer to VirtualGL, that seems like a great solution to some of the VNC problems we have. I've put together a wiki page describing the tksurfer 'sliver' display problem, and potential solutions, here: http://surfer.nmr.mgh.harvard.edu/fswiki/TksurferDisplayProblems Thanks to everybody on the list who has contributed potential solutions.
