Bug when adding directories/folders

First: great program, which has already saved me countless hours of manual renaming. Thanks for that.

But I encounter an access violation exception whenever I want to select directories ("rename files" mode) or folders ("rename folders" mode). After acknowledging the error I get an empty dialog where it should show the directory tree.
A couple of time I got the tree alright, but after selecting a directory and clicking "OK" the dialog closed without adding anything.

I'm using AR 3.65

Never mind. I seem to have missed the most recent update. It seems to be fixed in 3.73.

Hm, not quite, it seems. Adding directories ("rename files") worked twice. But when I moved to selecting a folder ("rename folders") it happened again. After that adding directories also showed the same error again.
Closing the program and restarting it helps temporarily.
