Haven't detected any problems soo far.
Better look at the update site there are problems. :'(
Bob, that is actually not quite the IE7 problem. It is how MailWasher handles those outside links inside e-mails. So I guess they use some old, outdated method or something... I have no problems with links inside incomming or outgoing mails with my Pop Peeper, also mail notification program, but much better since it's completely free of charge and unlike Mail Washer, it allows you to have hundreds of e-mail accounts defined and being checked. Also, you can define separate notification sounds for each account, or if you prefer some other (visible) notification add-ons.
Really it has no problems with IE7... maybe to contact Mail Washer team and notify them about this behaviour. I know that Alwil staff had to change certain things in avast! behaviour so it can nicely work under Windows Vista... same situation with MW.
EDIT: Also Bob, take a look in this thread:
http://forum.avast.com/index.php?topic=18018.msg153109#msg153109I gave an advice to that guy how to solve his problem. That sometimes happen when you change default browsers... let's say, you make MyIE2 your default one instead of the IE6 and one day you decided to remove/uninstall MyIE2... same situation with few other browsers. They will leave a mess with URL-HyperText Transfer Protocol...
I am pretty sure that's what happened on your end too... so in normal conditions, you would need to follow my advice from that thread, and I'm sure everything would go back to normal. not quite huge reason for uninstalling IE7 just because this happened on your end. Maybe even better, you weren't able to click any malicious links inside some incomming mails. Anyway, I never click nor read e-mails from within my mail notifier... it is there just to check my mails, and when I see what's SPAM and what's not, what's legit mail and what's not, then I process my mails and read them from within my mail client.
However, URL-HyperText Transfer Protocol problem is quite easy to fix... just follow my advice from that thread I gave you link for.
Cheers !
