In using Firefox 3.0.10 the WYSIWYG posting functionality presents blank dialogue boxes if you wish to add a picture, add hyperlink etc. In V2+ TinyMCE worked fine.
I crossed checked on a machine using Firefox 2.0.0.3 and all works well. Compared settings for Firefox and they are the same. Also, in using Explorer v8.0.6 there is no issue.
While I would lime to think it is Firefox V3, I am not sure given the configuration settings are the same. Does anyone else have this issue, if so I will backtrack through Firefox!
I'm using 3.0.10 (OSX) and I get the image box fine plus all other functions as well.
Is all related JS loading ok?
