>Thank you very much Sergey. Pardon my ignorance on this one please. I am slightly confused as to where the code would go for this since I am using a form. This is a small utility app which has a main program and one form only. If I put the class definition in the main program then do I simply check for the existence of the form in the custom resize method and if it exists run my code based on the resize of _screen? I have not used bindevent in this manner so I am trying to figure out how it all will hookup...

You don't need a separate class. You can create a method on your form called OnScreenResize with relevant code and bind it to the _SCREEN Resize in the Init of the form

* Forms Init
BINDEVENT(_SCREEN, "Resize", Thisform, "OnScreenResize")
