Weird issue with cftextarea/cfwindow

A while ago, I worked on an application where a manager can approve/deny xxx applications. When some body selects an action from a drop down, it open开发者_高级运维s a cfwindow and loads cftextarea richtext="yes" in there, so that they could enter reasons for approval/denial.

Now the culprit is that in production, the fckEditor has a ton of funky chars in IE8. Same thing won't happen in FireFox. Also, the IE8 does not show the same stuff in dev.

I have looked at the scripts in /cf_admin/CFIDE/scripts/ajax/FCKeditor, they are all the same.

Since this wasn't an issue before, I am not sure where to look at. Something got updated on the server which probably causes this problem. Does anybody know what could be the problem?

It turns out the vp put the header X-UA-Compatible: IE=IE7 in IIS to force IE8 emulate IE7. When I made them change this to X-UA-Compatible: IE=EmulateIE7, everything started to work perfectly again. For more details see Introducing IE=EmulateIE7.

Hope it helps others. Thanks.
