NB - Danny's response relates to toolbar buttons, *not* screen tips.
You could strip out the tip with code -
Selection.Hyperlinks(1).ScreenTip = ""
*if* you navigate manually to the cell first (arrow keys or F5). Even if you
do, you'll still get a tip - the address of where the link is to.
I'm concerned by "I don't have the ScreenTip button" - did you get as far as
a dialog box titled "Edit HyperLink"?
There's nothing on MSKB and very little on Google for screen tips - maybe
you could try re-register rather than re-install. Close XL, then Start --
Run -- excel.exe /regserver -- OK (make sure you include the space between
exe and /).
Other than that I'm in the dark.
HTH,
Andy
