O$: Instance name from Subwindow

[Fred Brinkman]

Bas,

No, I need the name of the class where the subwindow resides in...

$class().$name and $cinst().$classname give me the classname of the  
subwindow itself
$cinst.$class.$name and $cinst.$wind.$class().$name give me the  
classname of the window the subwindow resides in (the one I was  
looking for)

As always it turns out there's more than one way to skin the cat...

Thanks for your insights,

Fred
