Not sure if anyone's posted this but if you haven't already, disable the windows key in SC2 options. Also disable the clicking options for menu and hotkeys ingame, this can save you losing an army due to a misclick!
I was having problems with clicking the notifications/in game alerts too so I've turned them off as I couldn't find a way to just disable the clicking!
Mining tips:
Whenever you put workers with minerals into mining gas, press "C" on the keyboard and the worker will automatically transfer the minerals back to Nexi,CC,Hath before heading into gas.
