This is quite normal and happens, when you select more then one cell (a
range) all cells within that range, also bordered by a thick line, "turn
blue". This phenomen disappears when you select a single cell.

I have just started using Excel, setting up some basic forms. After doing a
few forms I have been geting light blue cells appearing whenever I click on
those cells. The same thing happens when I click on a row. I cannot find a
way of stopping these appearing.
