that feature would only work on a shortcut already displayed in IE
Only workaround is to convert the spreadsheet into Word then Save As html
then open that file in IE. That would work...

Hi,

How do I prevent excel starting a new instance of internet explorer whenever
I click on a hyperlink in a spreadsheet.
I have a spreadsheet with 3000+ rows. Each row has a cell with a hyperlink,
so the instances of IE can build up very quickly.
The IE/Advanced option "Reuse windows for launching shortcuts" is ticked,
but does not appear to have any effect.
