>Yes I restarted VFP 9 (I rebooted my PC). I do not have a lockscreen command in this form. I thought it was good. It is from yesterday when it worked. It stop working this morning. As far as I can tell the other forms are wroking as expected. Only this form shows on the blue (movable) section when I open the form. I can get to properties of the form.

What is WindowState for this form? Make sure it's set to Normal.

Other than that I may suggest to look for the yesterday's backup for this particular form.
