Alan
Good guess - I have a TMenuTree component which links to a TMainMenu and
uses actions to Create/Show embedded forms
The prob with using some form of Custom Message is that I wanted to keep the
thing standard - prob is there doesn't seem be anyway
that a form 'knows' that its ZOrder has changed - Unless there is a windows
message....
Thanks for your help
Neven
