I have a bug at this game, or something...
well the thing is, that when I engage in combat or am forced to do so, the characters with witch I play are not attacking by them selves and I have to pause etch 3 sec to put them to attacks, (oh and all besides Morggan) 
and no! It's not because of the tactics
so tell me forum... What should I do?
reinstal? do something in the game? is it really  a bug? 
please help!

Hit the "H" key.
 
If you're playing on another platform, just be advised there is a button that you can hit, forcing your party to hold their position, even while under attack. Just need to find it.

Yeah there are overarching commands like passive, aggressive, hold that affect what characters do.  

are you sure you've assigned combat profiles?

Do you mean that when combat is initiated they just stand there for a few seconds?

I think I've had the same thing happen to me and all I did was start attacking with my main character and everyone else followed.
