Please provide any additional information below.
This happens everytime at start-up preventing the addon from working. I know HandyNotes works since other addons are interfacing with it.

I just downloaded the new update, r16 (thanks for the quick update btw!), and it works great!

However, a new bug was just found. Actually, it's an almost identical bug and thus I didn't open a new ticket. Whenever you mouse over an icon on the mini-map it receives the exact same error. I looked at the code and saw the fix you put in and applied the same fix to the new line of code (which is line 275 of addon.lua, btw). This fixed the problem.

I don't know if you had mouse-over tooltips on the main map before, but they're not there now. I don't know if this was because of the "fix" I did on the code. If it's not there normally it is a feature that I think would be nice. I can open a ticket for this if it was not there before.

Thanks
