Internet Mail in avast! 4.5 Pro issue

I’m testing avast! 4.5 Pro again and i noticed a problem with Internet Mail provider.

I launched Enhanced Interface and created a copy of Real-Time scanning task. The only problem is that every time i change anything in this task Internet Mail provider simply dies. Its not paused and not terminated.
Provider in On-Access panel its grayed out and only Temrinate button is available. Also mail checking doesn’t work after that.

Seems like a bug, really. Please see http://forum.avast.com/index.php?board=2;action=display;threadid=8793 for a patch - that should help.
