When I try to open a file that I have previously worked on, I get a grayed
out blank window. No blank worksheet or anything. When I click on the office
button and click on open, the window for opening files comes up. I do not
click on a file, I "X" out of the window and my spreadsheet opens up. If I go
to Excel to open a new spread sheet I have no problem, it will open up a new
spreadsheet. I have uninstalled my Office 2007 basic and re-installed,
updated and still have the same problem. Any ideas???
