Same problem here. Same issue on ezoe or ezdhtml, rendering the editor unusable.
Are we the only one experiencing the problem ? Seems to be linked to FF 3 (on windows), at least it when hell broke loose on me with all the clients screaming on the tool ;)
Any suggestion so it works again more than welcome ;)
You can deactivate the OE and copy your text stricty into the textarea - does it not solve this problem? The are no formating anymore, but if you only wants the text to be copied.
