What steps will reproduce the problem?
left-click or right-click the LDB launcher, either on the text or icon.

Left-clicking on a recommended zone or instance to see Walk Path may or may not work.  I don't see any walk path, but I may be looking for in the wrong place.  I'd assume if we can figure out why left and right click to bring up the map or options panel doesn't work, then the solution for seeing a walk path will make itself apparent.  Shift+click does what it says it does and creates a chat link.

What is the expected output? What do you see instead?
Left-click opens the map, right-click opens the option panel.

What version of the product are you using?
r65

Do you have an error log of what happened?
No error is generated.
