When I try select Customise -> Internet Control Panel I get a message
saying "Error number -37".

I certainly do have a working Internet CP and IC extension. In fact,
this is a relatively new install as I re-initialised my HD a little
while ago. I can recall the pull down menu item opening the IC on
earlier versions, but as I've been using Fetch for years and uusually
open IC from the Apple Menu, I can't say which version last worked

I'm running Fetch 4.0.3 registered version on a Rev c iMac with MacOS
