Unable to use FCK or MCE editors in IE, can't post in Firefox

Yesterday I began having problems posting using the FCK editor and then later the MCE editor. I am unable to post at all with FCK and MCE reverts to aq version of plain text (except that there are no paragraph breaks). As Tony Isaacs using Firefox I am unable to post at all - I just get a large gray area where the text book should be.

I have run Ad-aware and AVAST anti-virus and then did a system restore - all with the same results. To top it off, the problem is NOT happening with the other computer (Luella's), which is networked to my computer which is the gateway.


Perplexing!
