The targetting computer window is most confusing. When you select items from the landmarks window to lock onto they show in the targetting computer window. In the targetting computer window the items change their order for no apparant reason making selection of the precise target you are interested in difficult/annoying at times.

This is not caused by the items changing their position relative to each other or any change in their status, the objects in the targetting computer window just move randomly.

To test:

Get 4 characters and stand them in a line when NPCing. Lock on to them all with 1 character. Dont move any of them. While fighting the NPCs watch the window that has all your alts locked and try to click on the one you want to repair.

Also, totally seperate issue....:landmarks window has a button that you can press to stop it jumping around like a maniac when you want to target something. Could this be made into an option to freeze the landmarks window when you mouseover it? Would be nice to not have to press another key every single time i want to lock something.
