There is a known compatibility problem with the link dialog in the FCKEditr version in iRtie and IE 8, we will be fixing this in an upcoming update to iRite.
In t he mean time, you cqan manually upgrade the version of the FCKEditopr that is used Here is some info on how to do that:
Before updating, I would strongly recommend backing up the WA_iRite folder. Also note that we have not tested iRite with any newer version of the FCKEditor, so we will not be able to support it.
In the WA_iRite folder, there is a folder called "editor", replace this with the "editor" folder in the FCKEditor package download.
Any other files that are at the root of the WA_iRite folder that do not begin with WA should be replaced with the new ones from the FCKEditor download. It is important to make sure you do not replace files that begin with WA.
Keep in mind, that if you update the FCKEditor, you may cause other problems. Also, if you add the functionality for Image Upload, you will need to redo the steps for enabling it.
