Thanks for the stack trace, it's indeed helpful, although I don't have this problem here.

Lister calls a lister plugin function, listplugin.ListNotificationReceived, which seems to trigger some kind of infinite loop, probably because the plugins sends a WM_COMMAND or WM_NOTIFY message to Lister during that function call, which causes Lister to call ListNotificationReceived again, etc.

I will try to catch this loop.

It is possible additionally will help to decide a problem.
On reference there is plugin and file which causes a problem. The other files do not cause an error.

Thanks for the test file! I do not get any crash when I hold PageDown, but the plugin hangs for several seconds in two locations of the file in PB6. These hangs are greatly reduced with my fix, so I assume that there is indeed some kind of loop (which stops sometimes on my system before the stack is filled).

Fixed in TC 7.50b7
Thank you!

P.S.:Now after opening of a problem file only:

plugin hangs for several seconds in two locations of the file

[ghisler(Author)]

Thanks for confirming the fix! It seems that the syntax colorizer has some troubles analyzing the file, which causes these hangs.
