I'm using "VMD 1.9.4a55 for MacOS X, 64-bit Intel x86 (x86_64)" in MacOS
11.6.1. The computer I use is a laptop and VMD seems to work fine. I can
for example select atoms with the mouse to measure distances. But
unfortunately, if I connect an external screen I am not able to pick atoms
anymore. Is this expected? Is this fixable? It is complicated to select
atoms in a tiny laptop screen.

Please let me know how I can help.

Thanks a lot for the great work!
