Thanks, great idea and it worked fine!
It was a bit of a déjà vu experience ... It took more than 2 minutes to load the folder tree (900+) but it did the job. It must have done some changes to some files as starting version 4.41 again reminded me that I have used an older version of PM :-) From what I could see no damages though only a few minor settings changed (fonts) etc. (really amazing) so, I just replaced my data with the backup copy after the exercise, saves searching for all the little switches.
However, I am impressed as
(1) I do not believe that one could do this (role back to an older version, several versions older) with many other email programs - try it with outlook ;-)
(2) Version 4.41 is really a lot faster (about 5 times - wild guess)
I am looking forward to the next version !! ... 4.50 or even 5.0? [ip]
Thanks
Thomas
