Thanks everyone for help.
The computer I'm using runs Windows XP, my task is to assist members of the library who have access to "upgraded" systems running Vista.
It's a stupid and bully environment managed by a lazy and fat Manager, I already too many times asked to have my system (which also has viruses) upgraded too but they just not listen!
As per information, I tried Photo Filtre from LiberKey and it works just fine, but I don't like it and I don't want to learn another software.
There MUST be a way and I'll keep searching, maybe Windows running from external source like USB drive or hard disk will sort this out...
