Accessing inventory on character requires multiple clicks to scroll from the equipment down to the next clothing (armor). While in the equipment slots multiple slots are highlighted at a time. When trying to scroll to vest it takes 3 to 4 clicks before the cursor makes in down to the first item in the vest.
If your in a backpack slot and you exit the inventory when you reopen your inventory the cursor is still in the backpack but the screen is only showing the top of the inventory instead of the where the highlighted slot is.
Occasionally when trying to close or open a clothing item (shirt) it resets cursor to the vicinity area.
