I bought myself a laptop for Xmas (nothing special, a $300 Lenovo) and everything works fantastic, but often a window I'm working in will not be active anymore. Not an issue when just reading stuff as i can scroll inactive windows by just hovering the mouse over it, but when typing, the laptop will start beeping at me when/if the window goes inactive. Sometimes the window will, in just a few seconds, return to its previous state all on its own, sometimes not.

I've googled around and couldn't find anything that fits what I'm experiencing and asked a IT buddy of mine
