>Is it possible to check to see if a form is already running so that it does not end up running twice? Thanks.

Here is what I do. Form references are one of the few things that I want to be global (by declaring them private in the main program). I create a variable for EACH possible form. The variable is initialized to NULL. When the form is instantiated, the variable will hold the reference to the form, so its type will be 'object'.

This implies that you can test the variable whenever you want to know whether or not the form already exists. For example, they can then be used in the SKIP FOR clauses of the menus. It goes like this:

Main program:

private goMainForm, goSecondForm
store NULL to goMainForm, goSecondForm

Declare the main form:

do form mainform name goMainForm

At times the second form is declared:

do form secondform name goSecondForm

Perhaps there is a check in an item of the main form's menu:

SKIP FOR not isnull( goSecondForm )

Get the picture?
