'tinyMCE.activeEditor' is null or not an object in ie8
I get the above error in ie8 when the Edit Content pop up box appears when I attempt to edit a standard content block. When I go to insert a file using the 'Add File' button and click on Choose from the drop down menu to select a file, the file will not insert. I imagine this probably has something to do with the error. Also, intermittently, I get an 'Object expected' error on - also on the Edit Content pop up box. Is this a bug with c5 or is it an issue with ie8? Has anybody got any ideas? I've Googled it to death without getting anywhere. Any help would be appreciated. We have a large client who, for a variety of reasons, cannot use any other browser other than ie8 and we need to fix the problem rather than simply use an alternative browser.
