I've now noticed that going from one level to another but then staying still causes a line of the previous level to be drawn over the current one, I think this depends on the differences between the new and old position of the player somewhat as it occurs every time in some places and others not at all, it can also be done with or without being on a gmap:
Regarding the playerlist alot of things seem really inconsistent, when you receive a PM you should be able to click the Icon at the top that has been changed into a PM bubble in order to open it, but this now doesn't seem to work half the time, mouse-over hint text also seems to display the wrong thing until you click somewhere on the playerlist.
It's also annoying that you now have to maximise both the client window and the playerlist window separately, they used to be in sync with eachother.
