I cannot open the bandmap if I am editing bandmap.py in an editor

[linustolke]

Describe the bug The Bandmap window does not open until I have closed emacs editing not1mm/bandmap.py.

This is confusing to the point I had to read the source code to understand why it didn't open.

To Reproduce Steps to reproduce the behavior:

1. Open not1mm/bandmap.py in an editor emacs not1mm/bandmap.py.
2. Start not1mm.
3. Select Windows => Bandmap
4. No window is opened.
5. Close emacs.
6. Select Windows => Bandmap
7. The bandmap window appears.

Expected behavior I expect the opening of a window, not to be affected by some other process on the computer.

Desktop (please complete the following information):

• OS: Linux (Ubuntu MATE)
• Version 22

**Workaround There is really no reason for having the emacs open while running not1mm so this is not a real problem.

Hi, it could be that there is an instance of it hung. not1mm checks if there is a process already running before launching another one. You could try:

ps ax | grep bandmap.py

Too see if there is one crashed but not closed in the background. Something like:

56114 ?        Sl     0:00 /usr/bin/python /home/mbridak/Nextcloud/dev/not1mm/not1mm/bandmap.py

If found kill the process and try again.

No, the ps ax | grep bandmap.py shows

1117487 pts/6    Sl     0:01 emacs not1mm/bandmap.py
1117520 pts/6    S+     0:00 grep --color=auto bandmap.py

and when exiting emacs, everything works again.
