Disabling the addon via the options menu will remove the guide display window from your screen, however, a /reload or logging out and in will cause it to display again, with the height of the guide display set to zero, and no guide loaded. Had to /reload after re-enabling to get it to appear properly.

Yeah, I'm testing it one more time here, but so far the error duplicates.

More info: to duplicate the error, I have simply disabled the addon from the wowpro guides config page, but have left the wowpro leveling module enabled. Upon disabling the addon, the guide window disappears. Relogging or /reloading will cause the title bar to reappear, with no data in the guide display. Re-enabling the addon from the Wowpro Guides Config page appears to trigger a refresh, but there is still no data showing in the guide display. The title bar reads "No Guide 0/1".

Selecting a guide from the list however, will make that list active for you, and you can view it in the Guide View window, but the data still won't show up in the guide dispaly unless you relog or reload with both the module and the addon enabled at the time of relog/reload.

Mostly fixed this. Using Ace addon, can't really load the guide in disabled mode. But it seems strange that someone would want to anyways. If they try, it will just renable itself without errors.

Currently coding is not set up well and we can't load the core without the leveling addon. So for now that is also always enabled on log in. It can be disabled once you are in, but it won't load disabled. For now. In the future we can fix this.

Calling this "done" for now, separating the core from the module is something I need to work on later but is a separate issue from this.
