Thank you for letting me know about it.

AbilityTimer detects the game window by searching the upper left frame.
for that reason, it will not work when upper left is hidden.

Could you try to use an application AbilityTimer which is created by me?-upperleftpattern.png

If it still does not work, please tell me the following information.
* Your OS version (Win 7/8/10 Home / Pro)
* Your Chrome version
* Quest (VS Typhon, Gem Quest, etc.)
