[chimerax-users] ChimeraX 1.4 frozen on RHEL 8.6 and 9.0

[Steve Chou]

Hi Greg,

Thank you so much for your detailed explanation!

I tried ChimeraX 1.4 (both the latest stable release and daily build) on
RHEL 8.1, 8.6, and 9.0, because it can only be installed on RHEL 8 or 9.
They all had the same problem (frozen after launching the GUI).

I also had an old daily build (04/12/2022) of version 1.4, which allowed me
to install it on RHEL7.9, but not RHEL 8 or 9. I'm running v1.4
(04/12/2022) on RHEL7.9 now because the helix cylinder functionality is
only available in v1.4.

All the best,
Steven
