Lock/Unlock camera also stop movement

This is something that happens to me a lot, since i started using MB4 to lock/unlock camera this happens, is a bug because there are games where is perfect and i can play without that problem and right now i have it again, that bug comes and go.

Please i'm not used to lock/unlock camera, but thats the best way to see the map and help faster, but since i have this bug is kind of annoying doing it because my character just stops moving or attacking.

TL;DR: sometimes the lock/unlock also stops my character from attacking and moving and i pretty annoying to play fast.
