Has anyone else had this recently...? Twice in the last few weeks I've visited CodeGuru and a popup window has appeared inviting me to participate in a questionnaire. Today, a window popped up - strangely blank (i.e. no questions) but with a title bar saying:-

http:://amch.questionmarket.com - No Purchase Necessary

I don't know if this was the same site as last time but the last window actually had some questions for me to answer (which I didn't). It hasn't happened with any other site and I haven't followed the link to see what's on the other end!!
