you might have to Start the Internet Explorer 7 in 'No Add-ons' mode
To start Internet Explorer 7 in 'No Add-ons" mode , click on Start, point to All Programs, click Accessories, System Tools, then click Internet Explorer (No Add-ons).
If the problem disappears after you apply this method, use Manage Add-ons to identify add-ons causing the problem. Proceed as follows:
1 Click on Tools in the Internet Explorer toolbar, point to Manage Add-ons, and then click Enable or Disable Add-ons.
2. Click on the name of the module at the top of the Enabled list, and then click Disable in the Settings area.
3. Click OK, and then test Internet Explorer.
4. If the problem persists, open Manage Add-ons, enable the add-on that you disabled in step 2, then repeat steps 1 through 3 for the next module on the list.
5. Repeat steps 1 through 3 until your problem is resolved or until all modules have been tested.
I hope this helps!
