I hope someone can help me. I must have done something by accident, but when I open any of my files in Excel, once I click on a box with my mouse, I cannot move to any other box, or even to the task bar, without highlighting every other box my mouse pointer moves across.

I am sure, or at least hope, it is a simple thing to fix, and I hope someone can understand what I am trying to explain. Any help would be greatly appreciated, as I am stuck and cannot do any work.

Thanks
