When using overridable EH, such as "InventoryOpened" and similar, where returning true allows to override default action, exitWith cannot be used to return value. So:
if (whatever) exitWith {true}; false;
Forget about it, will not work. Instead use:
if (whatever) then {true} else {false};
100% satisfaction guaranteed!
