Rex.

The method runeventcode should be in the button class. If you have not subclassed the base classes then I am not sure how to do this.

I have a similar situation that I use on my command buttons. I have a property "lActivateBindEvent" on my command buttons that I use to determine the behavior of my command buttons. I check this property in my init code and do the bindevent() only if the property is .t..

Another option if you do not subclass the command button is to create a method on you form that you can code to disable/enable your buttons.

I was thinking of looping through all buttons to get their state, saving them into an array, then restoring the state on closure of the called form.
