Character insertion breaking editor

After many hours of trying to find the problem, I think I did, so thought I'd post for anyone else running into it.

I'm using HTML editor for back end administration for my client to make changes on pages, filling a database table(s).

I was merely moving content from the older site and each time I worked on one particular page, either by cutting pasting, or typing in directly, the field using the HTML Editor, populated the next non HTML Editor field. It was very baffling, and was only happening on this one record.

It was the inclusion of a specific character in the edit box. Since there is a good possibility that it may happen here too, I'll insert the character followed by THE END after it. It may or may not show up!

THE END

It showed up! So what is different about this html editor and the one I am using? Some setting?

Thanks
