Mouse support?

Hi all, i have just tested the last retroarch version, i see that the mouse controller does not work anymore like old version (0.9.9.6). For me now with the new version is impossible navigate the various menus inside this program. How i can enable the mouse support? (now is impossible to scroll the emulator menus).

I have 2 android mini pc (cs 918) and the mouse support is essential to use retroarch. this problem is notiziable to my 2 tablets too (a asus tf300 and a alcatel one touch pixi 3 7").
