Gref, this is the problem!
NO ERROR message at all!
Just when I try to paste something it is not working
the paste option in the right click menu is not active!
I found in the net some similar problem with another model of canon and they sqid that thev can upload only jpg files - but I can not do even this!
I think that I will have to read the manual
(
Now have some free time and I will try some different options!
