IE7 minimizes on clicking links

Question

I am developing this website for a client. It was working fine till a couple of days ago on all major browsers.

Since yesterday I have been facing this unusual problem:

In IE7, whenever I click on any link on the page (navigation link or anything else), the IE7 window minimizes. When I restore the window, the proper link(the new page) is open and showing. Also, this occurs only if I have one IE7 tab open, i.e: if suppose I have two tabs on the window then it works perfectly.

Also, this works fine on IE6 and Firefox. Firebug shows no errors of any kind when I am loading the same page in Firefox.

Can anyone think of a reason that this could be happening?

Answer 1

• If you restore IE7 to the default settings, does the problem remain?
• If you disable Javascript, does the problem remain?

Answer 2

Yes. Its happening on multiple machines.
