Make Application always active

I want to make an application that I have on my startup be always active.

By active, I mean in use and ready for keyboard input.


I start XBMC media center on my computer's startup, but for one reason or another, another program may open (like if i plug in my mp3 player to charge it) and it will steal the active window.

That makes it so my remote no longer controls XBMC but will try to send keys to that new application.

I know i can solve the mp3 player thing by disabling autostart, but is there an app out there that checks to see if the window/application is activated or not then activates it?

i dont understand,u dont want ur computer to read ur MP3 player,but u want to charge it,if the computer doesnt alow it,how would it recharge??.managing startup entries is a different thing,but if manually plug in a device or open utorrent,u r activating it.A PC is not a TV or a Stereo
