Hey JCL,

I'm trying to make another user interface using the panel UNTOUCHABLE flag, and I hit a wall when I found that panel button functions functionOff and functionOver don't get called if the left mouse button is held down. This prevents mouse over effects when dragging an item, for example, highlighting in red to show that the item cannot go in the selected slot.

Right mouse works okay, so I thought the behavior may be intentional, but if that's the case then it could easily be created by the user with if(!mouse_left).
