Guild Wars 2

Any recomended fix for this issue:

Issue: Mouse Button Loses Focus and Does Not Reacquire It
Most of the time that this issue is present (it is inconsistent), the mouse actually loses focus and never reacquires it, which prevents character and camera orientation with the right mouse button and leaves the game in a completely unplayable state. Some days it is very bad and prevents you from even being able to play, other times it is only a couple times a minutes, but leads to frustration and not playing the game the rest of that day.

the link proposed by StinVec.3621 is dead

I use a mouse with a two extra buttons(Genius x-g510) that can be bind to keys (in this case 1), it will keep on doing 1 over and over and over until i release the button.

Before that just used Bomb kit instead of grenade because of pain
