How do I remove the gray paint (haze) from my text?
 

I've noticed on my spreadsheets that some of the text has a gray or black
haze or paint over my text. It almost appears I used the paint tool to color
over parts of my spreadsheet....which i obviously did not do. I can't read
the text when it appears. My laptop is a new MPC Transport T2300 w/ Windows
XP. I showed this to one of my companies IT guys and he had never seen it
before...Any help or assistance would be appreciated....it is really starting
to get annoying seeing as I used excel everyday at my job...

Thanks in advance!!!!!!!
