Description Stephen Herr 2012-04-10 06:17:10 EDT
Description of problem:
The javascript in the editarea RPM does not play nicely with IE9. Selecting text / moving the cursor is flat out broken and the text looks fuzzy. See http://sourceforge.net/tracker/?func=detail&aid=3081703&group_id=164008&atid=829997

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
1. Make sure that IE9's "document mode" is set to IE9 standards.
2. Attempt to edit text in an editarea window
Actual results:
Cursor always moves to the end of the text, you can't select text, text looks fuzzy.

Expected results:
It works as expected

Additional info:
The problem comes because IE9 actually correctly implements something that no other version of IE has correctly implemented. Editarea has some hack in it to do something like:
if ( usingIE ) {
  do some stupid hack to make it work right

and the stupid hack actually breaks IE 9. The following updates should fix the issue:
