I had the same problem, repeatedly at least until yesterday. My venerable 6 year old Compaq decided it was time to quit and showed me the Blue Screen of Death. My tech said it was hardware related and I'd be best to spring for a new one. At any rate, I bought a new 'puter, but was really concerned that my choice of operating systems was down to Microsoft Vista, of which I had heard a lot of bad things. But behold and lo... it has performed flawlessly, even accepting my Norton anti-virus program in just a few seconds. At any rate, I came back to Answer Bank wondering if it would still have the same problems... but it runs smoothly and quickly!
I think jno is on to something... I still run IE, of course, but it appears the different operating system with IE has solved the problem that I still think is inherent in Answer Bank.
Best of luck!
