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.

Does not happen for me with ARM Mac running OSX 15.7.2. Will try on OSX 14.

comment:3 by Eric Pettersen, 77 minutes ago

Should have said running ChimeraX 1.11

comment:4 by Eric Pettersen, 57 minutes ago

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.

comment:5 by Eric Pettersen, 50 minutes ago

Also failed to reproduce with 1.11.1 on an Intel Mac running 13.7.8

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?
