OK Ian, I agree the AppleScript worry is not a big issue!  However, 
it still leaves Windows!!

The ext_appsOpen() function in the current Externals collection for 
Mac OS Classic & X lists all open programs.  So it should be possible 
to detect whether some form of Acrobat viewer is already open on the 
Mac.  Once again, this leaves Windows to be solved!
