I assume that this was in Windows?
Jim

No, this was on linux (Ubuntu 20.04). And it was the "previous" 5.3.6 build, not today's one (I understand that that is only an update to MMCC).

(I also have a system running Ubuntu 24.04 at home, and I will take this evening to load MMedit 5.3.6 on it and confirm, since it currently has 5.3.3). I hope my issue is not due compatibility between current MMedit builds and the "old" linux 20.04, since 20.04 has always been very reliable for me.

Thanks for that.
I can rule out any funny Windows thing that's the cause.
That leaves me as the problem.

My Linux VM is 20.4 but I have recently loaded 24.04 on a spare PC.
This enabled me to fix the serial port issue and a few other things.
The test MMCC was compiled on that PC but I have gone back to the VM so I will stay with a combination that I know works.

@Jim,

Tried all evening on 2 systems (ubuntu 20.04 and 24.04) could not reproduce the lockup. Sorry if I mislead you.

I can go for days without seeing a lockup.
That is what makes it difficult to diagnose.

If it happened once on Linux that IS something to consider.

V5.3.7
Dec 2025
numerous bug fixes
AUTOSAVE N now works correctly with CRLF line endings
Linux now finds existing USB com ports
Note: if you are using fixed COM ports, you will have to add them to a list in the MMCC.inf file.

It is available from
https://geoffg.net/mmedit.html

The only download is a single ZIP which contains:

MMEdit5_32_64.exe
If you are installing on a 64bit OS, the 64bit will be installed
otherwise the 32bit version is used. Not for XP.

MMedit5_XP_portable.zip
Extract to a writable location. OK for XP and later.
The portable version writes to the application subdirectories only.

MMedit5.tar.gz
Suitable for Ubuntu 20.4 and probably later.
Also suitable for RPi Bookworm and Trixie

I have made changes to the Linux install scripts in a futile attempt to make it easier for Linux beginners.

Linux install.txt
Extract the files to a location that has permission to execute.
My preferred location is /home/user/mmedit5/

All executable files should have retained their execute permission but your
installation may be different.

In your GUI File Manager, navigate to the installation directory
and "Open in Terminal" or equivalent.

If the installation is on a RPi - ONLY on RPi systems.
From a command prompt run ./set-rpi.sh
This has to be run for all updates.

The first time MMEdit is run, there are a few support files required.
From a command prompt run ./getrequired.sh
This is not required for updates.
Depending on your version of Linux, these files may already be present.

To create desktop shortcuts,
From a command prompt run ./dtopscuts.sh
This is not required for updates.

The above scripts can be run from the GUI file manager but a command prompt will give more feedback.

Jim

Thanks Jim,

How are you doing ? Any improvement in health ?
