Hi

You have two or more sheets grouped. Right click on the tab of the sheet and
left click on Ungroup Sheets.
Any alterations you have made while the sheets have been grouped will have
been made to ALL grouped sheets.

I have a chart in a worksheet which until yesterday I was able to edit and
move around. Now I can't even select it, much less edit it. Insert
Symbol,
Chart, and Comment are all suddenly greyed out all the time. On the
header
bar, after the name of the file, it says [Group]. What have I done?
