Hotkey sends space bar out / pauses full screen video

[stevesmithtx1]

Still getting my barings with autohotkey, but after hours of trying to figure this issue out, I'm hoping someone can help. I pieced together a script from what others had posted that would turn the screen completely dark and mute and only lightup/turn on volume when the F5 key was held down. What I have works well...unless I am in full screen video mode which is the main applications I need it in (WMP, YouTube,ect). When I press F5, the video pauses as if the space bar key is being pushed down. I even opened a word doc and did notice that when F5 is hit, the space bar does jump from time to time.

Again, I'm a noobie so I could be missing something obvious, but I cant figure this one out. Any help of suggestions would be much appreciated! Code below
