In window mode with the RPOS up if you alt tab two or three times you lost the ability to right click on items until you close the RPOS and open it again.

Not sure what you would need from me for this. I was able to reproduce.

Also are you suppose to be able to right click on an item in the right hand side of the vendor window? When interacting with a vendor anything in the sell side of the window isnt able to be right clicked on. Relogged and the same issue
