The Mino Relic window is used to display the elapsed time you have been holding a Mino Relic.
The window will appear automatically when you pick up a mino relic. The Drop button is used to drop the relic and close the window.
There is nothing shown when the window is concealed. The window is invisible with no graphics or controls to minimize the amount of memory used. Nothing will appear on the screen when you attempt to activate the window.
