PointEntity and Quad Roll

Hi :)

It was a long time that i have post a blitz3d problem :)

But i become crazy with quad roll. Trye this code and press
key UP, you will see the sprite made a unwanted roll

And want only a camera facing, but without roll !! it is
possible ? I have search many solutions and informations
on the forum or code archive but i find nothing to help me ?
or i'm idiot and i have not very well search ? (possible)

I think that the POINTENTITY command is the problem, but
i don't understand how make some quad => camera/facing
without this function ?

Cheers
