Browser doesn't support frames

[DOTT291]

Hi,Toshiba Laptop, IE7 (then IE8), Kaspersky 2009, Vista Home Premium. Up to date on Kaspersky and Windows Updates. When running ie7 to access my Dlink Wireless Router I get the above message. Also, certain drop down lists don't appear, e.g. the list of support options when you hover the mouse over the support tag in Microsoft.co.uk. Some buttons don't work such as the exit button on "Do you want to download Google toolbar". This happens across al websites. Further when I try to print an e-mail from Windows Mail, nothing happens and the mesage just hangs - I have to use the task bar to dump Mail. I've tried resetting ie7, disabling (and even unistalling!) Kaspersky and Windows Defender, disabling add-ons, nothing I've tried has brought back full functionality... Don't think it's an ie7 problem, but then disabling security doesn't sort it either. My desktop unit (running Norton) works fine - so I don't think it's a Router issue??.....Any ideas, anyone?!!
