Unable to use 2 ui's
 

I use EQ2map and want to use EQ2interface, however I find I can only use !. If I run maps I cannot use interface. If I run interface I lose maps. What to do to get both to work together.

The interface files all need to be in the same UI directory. The game will only read from 1 custom UI folder.

Fully install the interface you'd like to use.
Download the EQ2MAP Auto Updater.
Run the updater -- if your eq2.ini is properly set up it should automatically detect your other interface and install itself into that interface.
