Don't know what happened. I didn't change any settings or anything. I was on a web page copying and pasting to a blank odt document and on about the 4th copy, I went to paste and the document would not open. This was an unsaved document. The icon where the document was at the bottom of screen is usually what looks like a sheet of paper with lines on it, however, this icon has changed to the OpenOffice icon - blue circle with 2 flying birds. When I move my cursor over it it shows the document I was working on, but when I click on it, it does nothing. Also, now I can not open ANY odt files, even ones I've saved, and the program itself will not even open.
I tried changing the compatibility mode to Win 7, but that did nothing. Any suggestions?
