I figured out if I right-click on the categories I'm able to use the journal, which is at least a temporary work-around. However, I'm noticing another click-related problem with inventory. When I click on things such as my stash or an item in someone's inventory, the click does work, but it also switches from one character to the next. This creates a problem when I attempt to equip an item as I have a character active, click on the item I want to equip and it moves to the next character. I can work around that by clicking the previous character first, however, when I then click on the appropriate item slot, it switches to the next character AND THE ITEM DISAPPEARS. It's no longer in the inventory, it is not equipped on any character and it's not in the stash. I've lost a cloak and two rings before I figured out what's going on and at this point I just can't equip anything that isn't a weapon. I have video, but apparently it's too big to upload.
