Tablet [Q] Disable the touchscreen

Hi everybody,

I have the following problem I dropped my Acer Iconia A200 and now the screen is broken. I can still control the device with a mouse through the USB-port. The problem is that the screen is generating random touches (without me touching the screen) this makes controling the device very difficult.

My question is....

Does anyone know an app to disable the touchscreen but leaving the mouse input option enabled.
If this does not fix the issue is there a software tweak I could preform to disable the touchscreen

Many thanx in advance.
