My personal experience with 4.5 (from the 1st beta till now)
- Problems when using Opera mail and the first beta (solved with the second beta)
- Still problems with the screensaver (had that already with 4.1, sofar not solved)
- Problem with rar files containing many files (80+, solved)
I know that the problems with Thunderbird (imap) are caused by the way TB is handling the mail, but there is a solution for.
Another thing I have noticed is that a lot of people using XP and Outlook (Express) and somehow the mail setup in avast4.ini seems to be wrong. I have tried to replicate the problem on my systems but wasn't able to on none of them.
Only this morning I though I had it replicate when the mail wasn't working, but it turned out that my ISP was working on their mailservers
4.1 back (temporary)? I would say no. To me it feels like giving blood to someone who is bleeding, but not doing anything to stop the bleeding.
