You could try delaying the update for 2 seconds?

The best I can think of is 'Hunt & peck'.

As I originally said, there is no perfect solution, but this works for
me. I know that Chris has difficulty with the second button on his TV remote
control, but we don't know how many tinnies of Fosters he has drunk!


Some 'style' observations:

1 - Why, in 'Do', add the line "self := NIL"? I think this just clears a few
bits on the stack immediately before handing them back to the system
to be overwritten by who knows what. Did you intend something else?

2 - After all these years I am so used to Oms's capitalisation conventions (see
Programming Conventions 'Docu\BB-Rules' section 8) that I find it a bit
difficult to read code written differently.

But I am in not in a good position to comment as I (usually) ignore some
of the other sections!

Cheers

Robert
