I'm no geek, but I've had probs for almost 3 months with similar.

Go to your security firewall and lower it to tollerant.

I couldn't believe that solved all my probs, but it has .....

I had ieframe.dll messages, I had "Firefox has stopped working, so to annoy you even more, Windows will close this program" stuff.

I restored backwards and even FOREWARDS sometimes lol

I uninstalled and reinstalled IE7 more times than I've had sex! (just a sort of example of my frustration folks)

I uninstalled MSN and reinstalled

I uninstalled IE altogether!!!!!

I tore my hair out

I tore my HUSBAND'S hair out

then ... 3 days ago, I went into my McAfee security account and did what some IT bloke said the problem was 3 months ago ... I lowered the firewall.

My world has now changed :D
