The only time that there is a difference between the use of the F9 key and clicking the talk button with the mouse button is when my program is being used.

The button will only lock when clicked with the mouse and works normally with the F9 key.

All my program does is blocks the button from getting a message that Windows tries to send to it telling it that the mouse button has been released so when you click the button with the mouse, it goes down as normal but it thinks it is still being held down even after it mouse button had been released.
