I wanted to find out if anyone has ever know a faulty JS code to cause something like this to happen, making search forms (or basically anything using <form>) to disappear? Is there anyway this can be debugged or fixed?
For some odd reason it rarely seems to happen in Firefox. I've loaded it a dozen times and the search form remains. It does disappear much more frequently in Safari and Chrome though. I'll have to use something equivalent to Firebug to test things out there instead.
I'm not sure, but there's something in the code that seems to affect how it breaks out when you click to expand the ad. Whenever this ad loads that's when the search form disappears, explaining why the issue seemed to occur at random.
