Command button goes transparent for no reason

Running a very large HMI program for a machine. Opens and closes many forms. For no good reason one of my command buttons become transparent. Just seems to happen. Once it does it stays that way till the program is restarted. The button still works but shows last loaded form even though the form has be unloaded. Tried to set the cmdbutton.visible to false and then in the form load code set it to true but this still does not stop it from happening. When the user hits the e-stop on the machine all forms are unloaded except for the initial form and the e-stop once i reload the the form with the transparent button it is still transparent.
