Hello Andi,
Sorry about the long delay in providing my feedback!

--- Code: ---Change History:
---------------
20250222 v1.9.0
- Skip sending lot of GUI (PM) messages for updating progress dialog with fast disks while copying and deleting files.
This is to work around PM memory leaks (crashes) when hammered with very much messages in a short period of time.
With fast disks copying or deleting small files takes few ms or even less. The previous logic to update the
progress bar after each file (and during a file when it is bigger) is changed to not send more than about one
message in 125ms. PM seems to be not safely ignore to much unhandled messages and starts to eat up shared memory.
Eventually this crashes the whole system when the process is not closed before. F.i. this skipps more than 69000
messages when copying the ApacheOpenOffice source code tree. The same skipping logic improves speed when deleting lot
of files. F.e. 33s instead 53s for AOO source code tree (about 70k files). More than 76000 messages where skipped with
that new delete logic.

Alright...this is by far my favourite file manager, so I do put it through it's fair share of paces.
Everything seems to be alright with the exception of the fact that the 'Bytes per second' window no longer shows the graphical throughput rate as the file copy progresses.
I repeated my file copy/move several times (between different SOURCE=>TARGET combinations and this is consistent.
So I left the above section of your post purposely because I now wonder if perhaps the "...Skip sending lot of GUI (PM) messages..." is the root cause of this???
Othwerise, things are good...thank you again for maintaning this !!!

Good catch. I wonder why I've overlooked this. Needs investigation.
