Description
The following bug report has been submitted:
Platform: macOS-14.8.3-arm64-arm-64bit
ChimeraX Version: 1.11.1 (2026-01-23 05:51:34 UTC)
Description
ChimeraX 1.11.1 and plugin Clix 0.25 on MacOS 14.8.3 gave me the following errors.
ui tool show CliX
QTextCursor::setPosition: Position '1' out of range
[Repeated 55 time(s)]
There is no error in ChimeraX 1.10.1 on MacOX or ChimeraX 1.11.1 on Ubuntu. It seems to be a MacOS only problem. Here is the related discussion on Clix github https://github.com/hanjinliu/Chimerax-clix/issues/59.

Could not reproduce using ChimeraX 1.11.1 on Intel Mac running 12.7.6.
Not sure we have a Mac running OSX 14, but I'll look around.

Hi Jianghai,
Can you try commenting out all lines that have movePosition() calls? That would be 4 lines in widgets/cli_widget.py, 4 lines in widgets/popups.py, and 1 line in widgets/hist_button.py.

I commented out all lines with movePosition(), reinstalled Clix, and still got the same error.

I'm not sure what you mean when you say you reinstalled CliX. You should edit those files in the already-installed version of CliX, i.e. ~/Library/Application Support/ChimeraX/1.11/lib/python/site-packages/chimerax/clix/widgets/<filename>.py and restart ChimeraX. Maybe that's what you meant?
comment:9 by , 49 minutes ago
Ah, I have a local clone of Clix. I changed the files there and reinstalled it. I also installed Clix through ChimeraX and edited files as you described. Both still gave me the same error.
