as this is an italian posting and as the mutual language of the forum is english I moved your topic to international subcategory (right now there’s no italian subforum, I’m afraid. Not enough requests for it so far).
If you want more ppl to understand your question feel free to post it in english (translate.google.com might help you with that quest).
from what I understood of your posting I have 2 hints for you:
please put as much information into your issues as possible… which machines, softwares, versions, configuration files, logfiles, etc. you’re gonna raise chances that someone would find a solution.
do serach the forum ahead of opening a new thread… always. Since I am pretty sure that there are already some nice solutions about your problem.
