Hi Everyone!

I randomly have a problem with some of my worksheets, and lately a lot more
often. When I open them, even before I select yes, run macros, about a
quarter of the right side of the workbook fully grays out. It grays out the
column headings, and all of the way down to even gray out the sheet tabs. It
also starts clear at the edge of the screen.

The only way that I can get around this is to open a blank excel document
first, and then open my working or "important" document.

Has anyone ever heard of this?
