Slowdown after repeated enter directory move operations.

Scenario:

Fresh copy of fman (downloaded 2025-04-05) running on latest Windows.

In one directory I have several hundreds of sub-directories containing one file each. I need to move the file from each of the sub-directories to another folder.

Procedure:

For each folder I repeat the following procedure:

1. Press enter to open the folder.
2. Press F6 to move the containing file (already highlighted).
3. Press return to confirm moving.
4. Press backspace to go back to start directory.
5. Press arrow down to step down to next folder.

Repeat a few dozen times. This can be done in less than 2 seconds per entry once muscle memory kicks in. Don't know if speed of operation matters.

Result

After a few dozen of entries you will notice a clear slowdown in step 4. It starts to take several seconds for the main directory to render and in that time you can not do anything. The filenames comes up immediately, but the icons and additional file info takes time. The problem gets worse the more you continue the above procedure.

Restarting fman brings everything back to normal (blazingly fast), but the scenario repeats every time.

On an end note I just want to say thanks for developing fman and bringing the power of NC to all major platforms. I use all three platforms on a regular basis and having the same tool on all machines makes my life easier. Keep up the good work. :)

Reproduce the repeated enter, F6, confirm, backspace, and arrow-down procedure on Windows with many subdirectories. Observe the delay while the main directory renders, especially icons and additional file information, and compare behavior before and after restarting fman. The issue names no files, tests, or entry points, so the affected code must first be located.
