touch controls for win 8 tablet

[lyhlyh7]

I wanted to play psp games on my Surface Pro, I turned on the "On Screen Touch Controls", and found that I had to DOUBLE-TAP on the key to press it... （Same for the buttons on ppsspp main window)
And multi-touch is not supported(as said above)

I hope this problem can be solved soon...

(BTW, Is ppsspp is the first emulator on Windows that tried to add a touchscreen support?)
