Created attachment 121824 [details] Calc file is a sample showing the problem I submitted When I type or copy an email address into a spreadsheet, it is normal until I hit the enter key. At that point, the text (not the entire cell) instantly has a gray background. The only way I have found to get rid of the gray background is to type ctrl-m. That removes the background. Sometimes, but not always, when I type ctrl-m, the gray leaves, but the address will be underlined. That can be removed with ctrl-u, as usual. Although it is a solvable problem, it is aggravating, as I use the Calc program for a directory, with each entry having an email address.
FYI, I checked to be sure the problem was evident on another computer. It WAS.
This isn't a bug. Tools -> Options -> Appearance Look for "field shadings." Setting as NOTABUG.
