Amanda,
This dimmed X button is an indication that you've got an internal dangling object reference that is keeping your form from completely destructing. Are you explicitly setting your reference to the OCX to NULL?
>I cannot make the form close using either the 'X' or the close on the form navigation bar. The 'X' button will dim as if the action has been performed, and the form nav bar will close, but the form is still on the screen. I have checked to make sure I have not overwritten the default form release function. If I remove the OCX control from the form, it will close. Any suggestions? Mayhap these OCXs are not being destroyed/released properly? A lockscreen? Does anyone have any experience with this?
