"Compatibility Mode" required to post a response under IE11...Running Win7 (64), and upgraded from IE10 to IE11.When I attempted to post a response on a thread, the "response window" had an error message and I was unable to make any entry.Since this behavior was exhibited immediately after upgrading to IE11, I added Zillow to the "compatibility mode" list, and was then able to post responses.December 04 2013 - US22YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
