Hi,
I have an ASP.NET application which can be loaded when clicking on a left navigation link on a custom entity. All was working fine, until recently I discovered that IE 9 and above fails to register/kick off an ASP.NET event (dropdownlist change). I believe this is an issue with a recent rollup (possibly 13).
If I run the application in a separate window (i.e. I copy the URL and paste into a new window in IE), it works fine with IE9 & IE10. Alternatively if I run the application embedded in the entity, but use chrome, mozilla or IE8, all works fine.
Basically it is a combination of a rollup 9 or above and IE9 or above PLUS embedding an ASP.NET application within a MS CRM window.
Anyone come across this before?
