A week or so ago I did *something* that has messed with my settings/config.
Now, with Excel ALREADY open, double clicking a file from Windows Explorer
causes a new Excel instance to start. Ditto when opening a mail attachment.

Other Office apps appear to be unaffected.

What's the solution? Anybody? Anybody? Beuhler?

In Options make sure "ignore other applications that use DDE" is unchecked.

If no joy with that................

I would suggest you re-register Excel

Close Excel first and On the Windows Taskbar

StartRun "excel.exe /regserver"(no quotes)OK.

See the space between exe and /regserver

You might have to designate a full path to excel.exe.

In that case StartRun "C:\yourpath\excel.exe" /regserver(quotes
required)OK

Gord - the DDE option was the issue. Somebody's add-in that I was trying to
test crashed Excel pretty hard. I suspect that was the villain.

Thanks.
