IE - Terminated Hung Browser Cleared Cache

[Falguni]

Hi

I have set private instance over Vista sp2 (32 bit).
I have turned off UAC and user have administrative access.
My Firefox test runs very well.
But when I run test on IE, It opens browser window but does not load url. It hangs at about:blank page. IE version is 9. I have enable debugging and following is what I found over log file.

Do you have an antivirus installed that may be interfering with the API hooking? Some Antivirus will work ok but some don't get along with WebPagetest at all.

I had not any Anti virus installed Bt somehow I was unable to notice "enabling wpthook" pop up when IE launched first time, and had disabled it. I think that was the reason causing issue with IE. I had tried with another system and that succeeded.

Chrome is also working ok with another system.

Thanks a lot for ur reply.
