IE7 delay

[Debaser]

Anyone come across this problem?......

When I try and close the IE browser, I get a very annoying 7 or so second delay before it actually closes.
I hit the X, then the page turns white for that 7+ seconds before it closes.

If I have more than one page open, the other pages close instantly , but its the last page open that always has the delay.

I always run spybot and I have also run ccleaner, but they have made no difference.

Thanks
