WowAce

What steps will reproduce the problem?
Minimap Button Frame installed and enabled:
http://wow.curse.com/downloads/wow-addons/details/minimap-button-frame.aspx
and EQQG also installed and enabled.

What is the expected output? What do you see instead?
I'm assuming I am supposed to see typical quest icons, yellow exclamation marks and such, on the minimap, but I see a few empty circles the same size as minimap buttons. These are shown for a few seconds, then they disappear from the minimap and appear for a few seconds in the Minimap Button Frame. After a short time they move back to the minimap, then again to the MBF frame, then back to minimap, and so on... over and over.

If I use the MBF slash command (/mbf remove) to remove a button from the MBF frame, the selected empty circle disappears from both minimap and MBF frame. I can remove all of the empty circles as they appear on the minimap until there are no more displayed.
So at least I can see the EQQG icons on the main map, but if I want to use MBF (which I do!) I can't get the display on the minimap.
But, when I move to a different area new circles appear and continue to move back and forth between minimap and MBF frame.
