Thanks for the response. I just tried that and it doesn't seem to work. Maybe I am doing it wrong. Where is the "Zone Map tab", to be sure? I open the Map (with M) and I see a tab labeled Zone Map. When I left click on the arrow I see three choices: Always Show, Never Show, and Show in Battlegrounds. When I right click it does nothing.
I also tried right clicking on the miniature map itself, to no avail. Nothing pops up at all.
