I'm using 2dtoolkit for education application development, it's really an awsome plugin for making a 2d view application in unity!
There are few buttons displayed on the screen, and my major bug is when i'm touching setting button and restore button in the same time, they both triggered! I had set Unity default api Input.multiTouchEnabled to false and make sure tk2duimanager is not using multi touch, but the issue cant be solved.
