Weird Tabbing Issue in Win7

So basically, programs (Namely Minecraft and Robocraft) are acting really funny lately.

Minecraft randomly tabs out and goes into windowed mode from full screen at random intervals, for seemingly no reason. Seems to usually happen when I click, to interact with the game or in game menus. Robocraft just freezes up for a second every time I click.

Other games have been behaving weirdly too, Chivalry takes forever to load, I'm getting unexpected crashes in CoD: Advanced Warfare (Might be unrelated).  

Does anybody have any idea why this could be happening?

My specs are more than adequate for all these games.

I'm on Win7 ultimate 64bit.

I really appreciate any suggestions!

 

Thanks,

Thanks for the response. I don't have any sticky keys set up, and I'll try another keybaord.

Oh, lol. My bad, no. And I even took all the keycaps off and air dusted it, cleaned it with alcohol wipes to make sure. Its a razer Blackwidow with Cherry MX blue switches.

I tested with another keyboard, same issue. Any other ideas by any chance?

Where do I go turn off gestures? Didn't know they were in Windows 7.  It seems to do it only in minecraft now, and is triggered by clicking my mouse in game.
