[DUG] Adding button to form

[Wayne Roser]

Hi Colin
Outside chance but I seem to recall placing a button on a form and seeing it at design time but not
at runtime because of some parenting issue. At design time, it looked like it was on Panel1, say,
but I found that it was really on the form canvas and was in the background at runtime. Anyway, it
is pretty easy to test this. Pick a button that works and add something like this to it's code:
	Caption := Button999.Parent.Name;
Where Button999 should be replaced with the name of the button that is disappearing. You might have
somewhere better to display the text than caption; chuck it in a showmessage if you are using the
Messages unit already.
