The player can look at a list of players in the public tavern by pressing esc. 20 players can be displayed in the list and the player is able to scroll with the mousewheel up and down. If the player scrolled down then the list is only visual scrolled, but the player entries in the list still stay at the same possition. So if the player selects a playername after scrolling, he will click on one from above.
Steps to reproduce:
