Dear Gianluca,
here in Zadar (on AAKR) there is a little army of testers of CataThumb. And we have one problem, that is occurring on several computers, either with XP or Win7. When you start the program, set all the parameters, it starts working and everything is fine. Now, when it comes to the last photo, is won't stop, it's not finishing. I attached a screenshot of the situation (in my test folder I had 41 photos, it processed them all and then it stalled..). In the background, everything is done (thumbs folder, xls file), but every time you have to force close the programme, it simply freezes. We figured out that you must not have another thumbs folder, because it "confuses" it, but the problem still exists.
I hope my explanation is understandable, if not, I'll try again! :)
Cheers!
Andrea
p.s. and thank you! ;)
