Mobile controls, gui mouse problem.

Ive got a control bar, it has 2 sprites on the left side (for movement) which respond to touch,

three gui buttons in the center of the bar (spells/ablities) which respond to the mouse,

and two sprites at the right side of the screen (jump and inventory) which respond to touch.

I didn't figure out that in case of more then one touch the mouse position will be between the touchs, and now when I attempt to use the left side buttons and the right side buttons together a mouse position is detected at the center of the screen pressing the abilities buttons...

Is there a way to detect the gui only by touch? or a way to make the mouse position focus only on one touch?

Consider that I might also want to use the spells/abilities gui buttons with the movement / jumping sprite buttons...

Many thanks for anyone who helps!
