Can't assign shortcut that is really not assigned?

Hi!

I want to have the same set up I have in my rMBP 13" and the app Lightshoot Screenshot, which is to use ⌘⇧4 (yep, same as system's) in this app.

When I try to assign it, the app says that it can't be used because it's been used by the system. But I've already disabled it from system prefs... So what's going on? I even rebooted, windows style didn't help.

I swear in my laptop works, and I don't remember doing anything different.

You may have to change the system assignment to other keys, not just disable the assignment.
The system defaults may continue to be maintained by the system, even though you have disabled them.
Try leaving the settings enabled, but change the system key combinations to something else.

I feel a little dumb now... Yes, that was exactly what I needed, it worked.

Thanks.
