I will put it on ask or turn it off then. Thank you for your help. Also have there been any FP's before for the sandbox?
Eh, technically no. It flags things only as "suspisious" or not, so since it is never "positive" about anything, a FP is technically not possible.
But technicalities aside, it has sandboxed things everyone and their mother knows is safe before, yes. But less reports of this (here on the forum anyway) since it was first released till now.
