ckeditor firefox 4 fails to bring up image and other dialogs

Perhaps further context might help.

The editor can be attached to an editable area. However bringing up dialog boxes - especially with images, seems to be the problem. I am also using shared spaces. . I have found that that other dialogs like the table have the same problem. Has the code been tested with shared spaces and attachment to more than one editable area at a time? If not, do we know how it will behave in these scenarios?

Thanks again for your help.

One more thing: I am using Firebug, and when it is active for a page, it pauses on every publish() and exec(). I have not enabled any breakpoints but I have "disable break on errors" active. If it is deactivated - everything works. Note also that this failure is silent - no output appears on the console. So unless a debugger is enabled it won't surface to the user.

I hope that helps.

Thanks.
