Hey Jim, that would be to avoid flashing in Windows when changing views and can be done anytime.
Another tip for the keyboard number pad is to get rid of all default FSX assignments so they do not conflict with your EZ number pad assignments! Personally I keep
the differential breaks for certain tail draggers!
An easy way to see what is assigned to a key or joystick button is in FSX/Controls/All Views pick a line that has NO key or button assignments, choose Add New Key/Joystick
Assignment and a window will pop up telling you the key/button is clear to use...OR...what that key/button is assigned to! Saves a lot of time scrolling and maybe missing something!
