I've a problem using IN_USE button in some cases...
An example:
I'm hooking IN_USE button in CmdStart, and when it is called it is created an 'X' entity, like a rocket. But sometimes when I try to use an object (button, door, anyshit) my hook it's called, and the rocket it's created unusually.
How I can prevent to call this hook ONLY when the user is not using an object?
