--- Comment #4 from Rosanne DiMesio dimesio@earthlink.net 2012-07-30 13:14:38 CDT --- I've always used Firefox, and I just reproduced it on the FAQ page in Firefox 14 on Linux. All I did was open the page in Edit mode, then click "Save changes"--I didn't even MAKE any changes, but the preformatted sections that have more than one line are now a mess. I've left it that way for you to see; it will need to be reverted shortly.
