try pressing F8. If that doesn't fix it press it once more to turn that
option off. I often run into that problem when ever I am using Macros by
****ing the Alt key. Does it select a bunch of cells from the active cell to
the one you click on. F8 would be the cause of that.

I am trying to start a new spreadsheet, however, when I click in a single
cell a range of cells turn blue. The number of cells that are selected is
never the same.
