Eivind posted a workaround for some basic functions in the other thread using shortcut keys and I can confirm they work. Edit: Heh, speak of the devil ;) Eivind said: Dapper, as a work-around: You can use hotkeys to go around the right mouse-click issue. It's annoying but workable.

Right Mouse Button+Drag: Pan
For the devs: I took a look at the help menu and I found that holding right mouse button is meant to make it pan - which is what I am experiencing. I think the problem is the website is not distinguishing between simple right-clicks and dragging/holding the mouse down.
