Hi,

For the GuiButton, on Windows the bevahiour is good, with the mouse the button is highlighted then go back to normal state but on Android the button stay highlighted when touch it and release, I need to touch the screen some where else to go back to normal state.
I have tried to used GuiSetState but no success
