Did you perhaps inadvertently update your video card drivers? If that is
the case, navigate to the Display, Settings, Advanced, Adapter, Drivers
and then Rollback.

I have Excel 2007 and all of the sudden am missing gridlines in Excel (and
also in Access query design view!!) In Excel, I have gridlines checked under
both Page LayoutSheet Options and ViewGridlines, I have no borders, and the
cells have no fill.

Where did my gridlines go??? Please help.

Thank you,
