I am in need of help in identifying a problem with a workbook that has 9 worksheets.

The problems is that certain area's in the worksheet will turn the cells background blue in Worksheet A, and in Worksheet B the cells are blue but in a different area. Worksheet C, D, E are the same as well, but different areas. In Worksheet F & G only two cells will be blue. The last Worksheet is not affected.

Any help would be greatly appreciated. This happened once before about six months ago, but I started another spreadsheet and the problem was no more. Though I never found out why it was changing the backgound color without any input from me. The previous problem turned the cells green.

Even when I change the background color back to white and saved the file it would change back when the file was opened.
