MS Office slow opening and closing
I've had MS Office on my laptop pretty much since I bought it over a year ago (used). It came with Office Libre, but because that wouldn't display some of my Excel graphs correctly, I Installed an old copy of Office 2003 I had and it worked fine. But in the last couple of weeks any Office documents have started to take an agonizing 30 seconds to open and close. I ran my virus scan and it didn't help. I searched on line and found no solutions. I installed Office 2007 (I didn't want to go any higher because they're way too weird) and it didn't help. Right now I'm back to using Office Libre because it's so much faster, but I much prefer MS Office. Any ideas?
I have Windows 7 Professional.
