Queue for BG when popup show
If you right click on the minimap BG queue icon and select Enter BG it works,
But it is not working if you try to enter via popup window showing in the center of you screen,error is "ORA3 has been blocked from an action only available to the Blizzard UI. " I then have the option to disable or ignore the error. If i disable addon everything is fine.
