[chimerax-users] security bug in ChimeraX 1.1 and earlier on WIndows

FYI, ChimeraX uses the Qt user interface toolkit, and recently a security bug was found in it on Windows.  It affects ChimeraX 1.1 and earlier.  See https://kb.cert.org/vuls/id/411271 for details. Our recommended fix is to update to the current version of ChimeraX.     -- Greg
