Keyboard/OpenGl doesn't work until button is clicked.

[Jonathan Haws]

My GUI is working great, other than an issue that is annoying.

The keyboard commands that I have implemented don't work until I click one of the buttons in the GUI.  It can be any button, it just needs to be clicked and process something before the KB will work.  It is really annoying and I have checked my function to see what it may be, but the GUI doesn't seems to accept any keyboard input until a control is clicked with the mouse.

Any ideas?
