This may only be an issue for people that are upgrading, but I'm getting the following error:

Message: ..\AddOns\WoWPro\WoWPro_Frames.lua line 261:

Debug:

WoWPro\WoWPro_Frames.lua:260

At best guess WoWProDB.profile.anchorpoint is nil.

Set a default of TOPLEFT if it isn't set before doing all the checks. There may be a better place to set this?

This is what happens when I code at 4 in the morning.

Added an "auto" setting which is chosen by default, which finds the quadrant the guide is in and sets that corner as the anchor point.
