Invisible Minecraft window?

Okay, so i'm using the latest version of forge (so i can use shaders) on minecraft version 1.7.2, and i start the game as administrator. Then i look in task manager, and i see that javaw.exe is running… But there's no minecraft window. Anyone know why this is?

There are children starving in Africa, and you're concerned about this?!

(Also, this can usually be fixed by going to your task manager and forcing minecraft.exe and/or java to close in the processes tab. This is common with alot of programs, because they hang behind the scenes and stop any new session from opening.)
