Does this mean that if you double click on a .xls file in windows explorer, then
Spanner starts up?

If yes, try reregistering excel so it owns that .xls extension.

Close Excel and
Windows Start Button|Run
excel /unregserver
then
Windows Start Button|Run
excel /regserver

The /unregserver & /regserver stuff resets the windows registry to excel's
factory defaults.

Then test it out.
