Thanks for that - but with ref to Viewfinder - I've gone back to 1.44
(27 May 2002) (without testing them all) - bit of a guess - but at the
moment works ok.

Is there a list of ways to print to the screen available?

So it could be tested - which method/s might have been removed - in
later versions of Viewfinder - or indeed the OS.

Thanks
