I see. I am about to give up on IE at all. I have nothing but problems with IE. The latest one is that when I run a simple test form with Bootstrap.css the IE ignores all the Bootstrap rules. The same page in Chrome works. Even when I open a simple page in Fiddle in IE the bootstrap rules are ignored. And the same Fiddle in Chrome works. Very frustrating.
