Joshua,
  Yes, I've known about these event handling issues for some time.
While they aren't fixed yet, at least we no longer have to modify
the Tcl/Tk source code to prevent crashes anymore! I used to have to
apply patches to the Tk source code to change some of their event handling
code to prevent Tk and FLTK from interfering with each others windows.

I've mentioned to the Apple guys a number of times that they ought to
see about improving the MacOS X Tk port, since I believe that Tk for
MacOS X was originally donated by Apple engineering staff. The other
issue I have related to this is that the current Tk for MacOS X is
based on Carbon, which precludes building 64-bit binaries.

I may end up making a future VMD build for MacOS X that's based on X11
rather than the native windowing system, particularly if that allows me
to build 64-bit binaries.

Cheers,
  John Stone
