>Hello folks,

>I have a form called hugform (the name is "hugform" and the scx is "hugform.scx"), which can behave in various ways depending on the setting of a global variable. How can I tell whether an instance of this form is already open when a menu item is selected, so that I can ensure the existing instance is released?

well. make a class from your form (Save as class in menu when you have the scx opened in editor). and then instantiate your form like"

if type(goHugForm)=[O] and !isnull(goHugform)
   goHugform.release()
   gohugform=.null.
endif
gohugform=createobject([hugformclassname])
gohugform.show()

and of course, you have to declare public variable gohugform otherwise your form will be closed as soon as variable will
go out of scope.
