Hi,
Depends on what's causing that. Vista slows things down, Excel 2007 is
slower to launch than 2003. If you are launching it by double-click a file
in the Windows Explorer, it is having to open the file also, that slows
things down. Too many programs open will slow it down. A slow of too many
anti virus programs may slow it down. Too little free hard disk space, will
slow things down. A highly fragmented hard disk will slow things down. You
can add more RAM, you can clean up your hard disk and defragment it, you can
get a faster hard drive.
And I'm sure there are many more reasons.
However, here is the ultimate question, if you open Excel once a day why
would you care if it takes 1 minute to open? On the other hand if you are
opening it frequently, then why not leave it open and just minimize it.
