Hi,
  This is a bug in the behavior of TkCon w/ Tk 8.6, which is required
for MacOS X Catalina... I'm working on updating the TkCon version we
ship with VMD to a newer version that should hopefully cure this,
which I also described briefly a few days back on the mailing list when
this issue was mentioned by others.

Best,
  John Stone
