Action RPG Inventory System

I have a couple of glitches that I am sure are the result of not applying an update somwhere.

The first, longstanding one: items do not always highlight to be used. Sometimes I have to run off, highlight another item, and come back.

The second, occurring lately: closing a container sometimes disables the mouse and I have to esc to a menu (not a ARPGIS menu) to get it back

I’ve done a few searches on the thread, but apparently did not come up with the proper search terms. Could anyone point me in the right direction?
