TOPIC: Email tab Editor not displaying in IE

Just posting this in case anyone runs into a similar situation.

We have a client running DTRegister on their Joomla 2.5 website and when they're formatting Events in newer versions of Internet Explorer the Editor window under the Email tab doesn't appear. Displays fine in Chrome and Firefox and oddly enough IE 8 but IE 9/10/11 wouldn't display the editor.

The site was also using the JCE Editor and that's where I found a temporary fix.

Current Configuration:
Joomla: 2.5.24
DTRegister: 2.8.13a
JCE Editor: 2.4.2

Changing the editor back to TinyMCE or installing a previous version of JCE (i.e. 2.3.4.4) resolved the issue.

For security purposes I prefer to keep things updated but until I find out what's causing the conflict it looks like I'll need to hold off.
