[Chimera-users] problem picking atoms in graphic window

I have a peculiar but simple problem using Chimera [version 1.13.1(build 41965)] on a Windows 10 PC-computer]. Using it to model docking of small molecules to an RNA using autodock vina. This has worked fine.
Recently wanted to measure distances by control-click on atom 1 and control-shift-click on atom 2 (picking the atoms in graphic window). Nothing came up in 'Structure Measurement' box when I 'picked' the atoms and clicked on Create except for it telling me I had to pick atom 1 and atom 2.
If I hold the 'control' key of the keyboard down and move the mouse's hand symbol around an atom, the green outlined shape does not remain when I lift my finger from the mouse. On the right side of the bottom bar of the screen it says 'selection cleared' which disappears in a few seconds. When one holds both control and shift keys down and encircle the green shape around an atom, the outline remains. Control click in an empty area removes it, as it should.
A postdoc in an adjacent lab who uses Chimera took a look and was puzzled since her downloaded version on her computer works fine in picking atoms etc. She also was puzzled since my mouse arrow when moved over an atom/residue did not show what residue it was, which apparently it should. We tried several pdb files (proteins and an RNA) and they all behave the same.
We checked under Preferences that the matrix of radio buttons for my mouse's actions were set the same as hers. Is there some other preference setting I do not have set properly? Everything the mouse should be doing with regard to moving/rotating molecules is as expected, and the program otherwise appears to work fine.
Any/all suggestions on solving this 'picking' atoms problem are most welcome.
Thank you and the others at UCSF who have developed Chimera.
