I use Excel version 10. Up until this week I have been able to highlight a cell in the worksheet, select the home tab, select and execute a command. I could again highlight a cell, select another command from the home tab and execute.



A few days ago something changed. Now I have to highlight a cell in the worksheet, select the home tab, select and execute a tab and upon doing so, the tabs disappear. In order to recover the commands, I have to highlight a cell in the worksheet, select the home tab again and find the command.

How do I fix this?

Do you mean that the Ribbon collapses so you can only see the tab headers? If so, double-click one of the headers.

The ribbon disappeared each time I clicked on a cell in the worksheet. I just tried double clicking on the tab and it seems the problem is solved. Thanks!!
