ESC always operates on the top most window. No way for me to make it close bottom most.
The Map and Inventory windows were made to ignore ESC by popular demand. They can be toggled easily with "M" abd "I" respectively. No need to use the mouse.
To re-enable ESC for Inventory, open eq2ui_inventory_inventory.xml in Notepad and delete this code bit...
Code:
allowcloseontop="false"
To re-enable ESC for the Map, open eq2maps/skinable_WindowElements.xml in Notepad and delete...
Code:
parent.allowcloseontop=false
