iMatch hang on closing

[Carlo Didier]

iMatch hang on closing. It seemed to close normally, but when I wanted to open it again, it said there was still an instance running. I had to kill it in Task Manager.
Here are the last entries in the event log. I "closed" iMatch at 15:50.

That's unfortunately no debug log so the info is limited. Can you attach the full log please anyway.
One reason might have been that IMatch was unable to detach from an exiftool.exe process and that the process refused to close. Can't see that in this log snippet.

Do you run scripts?
Did you use drag and drop to another application?
Maybe added a PDF file?

[Carlo Didier]

I don't have this log anymore. Should have made a copy, I know. No scripts running, no drag and drop to another app. I just closed iMatch as I didn't need it at that moment.
I think I'll just run it in full debug log for some time in case the problem re-appears.

[Mario]

When an ExifTool instance hangs, IMatch waits up to 3 minutes and then tries to close it forcefully. If this also fails, and Windows cannot detach IMatch from the blocked process, IMatch may be hanging. But then usually warnings and errors are logged (in all log modes) but your log snipped does not show any of this. I can't say more without more info, unfortunately.
