For the past day I have had problems using the editor as although the frame appeared with the buttons, it did not display any text and would not let me enter any in the main box. I tried Netscape and did not even get the htmleditor just the plain text one. Tried all the forum lists and tried the suggestions to no avail.
After much playing the solution eventually lay in the fact that I use zonelabs and had selected the option to stop adverts including popup/popunder. When I turned this feature off the editor worked fine every time . I have since loaded the google toolbar which also includes a stop pop up feature, but this does not affect the htmleditor so I assume it must be the popunder feature in zonelabs.
I thought I would post the solution to my problem incase anyone else experienced it in future and has software blocking pop-unders.
Kind regards
Ian
