I've got an issue with some excel files. When i work in a workbook some of the lines turn black.
I don't use conditional formatting in this workbook.
The file is created in office 2007
I'm working with excel 2007
Windows 7 64 bit with office 2007 32 bit
Not only the cells turn black but also the line numbers.
When i select a black cell, and i start scroling, the text in this colom reappears. as you can see in the two screenshots i've attached.
Does anyone have a suggestion for this problem?
