I don’t seem to be able to drill down into some major websites anymore. Can anyone suggest what the problem might be?

For example, I can log into my bank’s website and see all my account balances but then I can’t drill down to see the transactions. I can get onto Gotalk’s website to see my home page but then can’t drill down to select my service to see the balances. I’ve also noticed that my Yahoo calendar does not display properly. It only shows the times of the appointments, not the details. 

I have a Toshiba laptop that’s 3 yrs old. It runs on the Win7 operating system with Internet Explorer ver 9 as my browser. As far as I can see, apart from this problem, it’s in perfect condition and all programs run normally. I use McAfee protection software which regularly scans the disks and tells me that my computer is safe.

I have used another laptop computer on the same broadband account and it works fine. I’ve also checked my internet usage and I’m well within my limits (only used 50% with 2/3 of the usage month gone). I don’t think it’s anything to do with “popup blockers” either. If I turn them off it doesn’t make any diff.
