Greetings. In the last versions of Sexymap the location of the default questtracker-mover is not saved. I'm using the 'Simple Square' preset. Happens when the movers are 'locked'.

Before reload:

After reload:

Can confirm this issue in Classic. It becomes even more annoying, the bigger you scale the minimap.

A workaround for me is to go to the options into "moveable buttons" (i have the german client), uncheck and check again "lock movable buttons", and there you go.
But you're right, it resets itself after every UI-Reload.

Why is this closed without comment?

It's unlikely this will be fixed for Classic, but should be fixed now for Burning Crusade Classic.
