>Does anyone have a way of preventing multiple instances of a form without setting the Form WindowType property to 1-Modal?

I beleive you'll only receive general ways of accomplishing your task until a little more is known about how and where you are calling the form form, if from another form or a menu. If you are calling from your menu just issue a *skip for WEXIST("formname") and that option will be disabled when you refresh the menu. This will be by far the easiest and less cumbersome way of doing what you need.
