I am working in Excel 2007 and XP, when I click on a cell - automatically several (7 this time) cells are selected. I left click on the row number and again multiple rows are selected. To get just one row selected I must move my mouse up and then it un-selects rows until I get to only one row selected. I have saved, closed the document and the application and it does the same thing. I checked the scroll lock and it is not on. I am getting extremely frustrated. Can someone please tell me how to make it stop?
