I don't know how to describe... This is about editor, I think with html5 doctype and IE9 (I'm using, post-beta leak, not RC yet) (at least at my test build) for instance, "selecting a text range" like "text" word and pressing bold makes it like "[b]tex[/b]ext" not taking entire word or adding extras... (with Quirks mode like here, it works okay, so one side is related to DOCTYPE)

Not quite sure problem. It does not have problems in IE8 mode or any other browsers, so will watch out for real RC...
Other issue is sadly javascript "prompt" command asking a security question in IE9 on Prompt mode... Trying to find an alternative for that, but no thirdparty javascript halts and wait for responses like prompt...

Thanks, will try asap...
Seems only way to find out is to wait for next release and see if it is fixed (if bug --which is most likely)

it could be that the javascript in the forum just needs updating

might be, but then again, this happens not only on Snitz also Discuz!, vBulletin as far as I tried. Well, will look for solutions meanwhile...
Edit: OKAY, seems problem is selection moves exactly as count of "\r" characters which IE9 also supports \n only are carriages. Problem does not occur at first line, but following lines after enter/returns (which might mean IE9 returns character count wrong or misinterpreted also)

ok found it, demo here http://demo.vishalon.net/getset.htm (sets and returns correct caretpos in IE9

code here http://blog.vishalon.net/index.php/javascript-getting-and-setting-caret-position-in-textarea/

IE9 RC is out and yes, as I expected, they have fixed that problem it seems :) So no need to modify any code unless if you think it would be improvement....
