  The latest Apple Big Sur operating system has broken the behavior
of many applications (like VMD) that use cross-platform graphical
user interface toolkits.
We don't have a solution for this problem presently, but we are already
testing new versions of the GUI toolkit libraries VMD uses to see if
they might address the problems with Big Sur going forward.
At the present time I have no estimate of how long it might take for
this to be solved since the problems are not related to any VMD code,
and involve only software written by others.

When we think there's a solution, we will make it clear on the
VMD web site and on the VMD-L mailing list.
Best regards,
  John Stone
