Helo,
I have some problem with login in different sections of these forum.
I think it can be done because a change in my profile my be done in one section but not in the whole forum.
When I change from one section to another sometimes I'm loged out.
When I look to my profile, from some sections is the new and from other is the old.
For instance many problems are in the AFCAD&TTools section.
Please have a look, when you have time, don't worry, it's not in a hurry.
I seize the oportunity to thanks a lot all the team working in these great site and forum, has been a pleasure to find it.
Kind regards.

Thanks Pete,
The problem has been solved.
It has not been a problem with cookies but was the expoler's configuration that allways takes form temporary folder, the page opened before.
I had the same problem with other forums and than I thought it should be something like that, and yet it's fixed.
Many thanks and kind regards
