Looks like both yours and the default one are ignoring their resized values and revert back to the default size when camping back to the toon or logging back in. Link to my thread about the default on in the EQ2 forums:

Every time I resize it, it adds another container_clone_# entry into the settings file. At the moment I'm calling this a SoE problem as it happens with the default window.
