I'm pretty newbie on Mac.

I wanna open Xcode, when I clink on the icon, nothing happens, not a warning or error, the icon jumps a little bit then stops and thats it, no Xcode or loading screen etc. I can see the Xcode icon when I hit Command-Tab, but again when I click that Icon, nothing happens.

As if it is already opened but cannot be accessed for some reason.

Since I am a newbie in Mac, I dont know how to try to find the error(if any), or try to debug it. How should I approach the problem.

(Should I uninstall and reinstall like good old windows)

Version is Mac OS X 10.7.3
