Jts game and PC in tablet mode

[KhanDam]

Hi 
I use an hp PC envy x360 who can be use in tablet mode ( without keyboard nor mouse )
Jts game work correctly but I can't make right click with my finger or with the stylet ( normaly with finger I stay long on screen and the system simulate a right click, same thing with stylet or use the stylet button )

But jts game don't handle right click

Have you any idea or clues to make it work
