Ben's follow up this morning reminded me that I meant to
ask about this.

Do you have evidence that a CATCH statement is slow?
I pretty much put CATCH error handlers in ALL my
event handlers, including those used in draw widgets
for motion events. I have never noticed that these
were "slow". Or, rather, I've never thought speed was
a problem for anything I was doing with motion events.

Cheers,

David
