Tested on trunk, svn revision 43057.
In the second screen (Idol), if you take the umbrella (ombrello) and use it on hot air (aria calda), and then look into the interstice, you'll trigger an animation with Blount getting in love with the girl. After the animation the control goes back to the player, which can move around the characters, but at this point scrolling is locked in both left and right direction. The inability to scroll the screen makes the game unfinishable.
It's notewhorty to signal that i've been able to reproduce this only on Italian DOS Floppy version. Both English DOS CD version and Windows French version (found on ADI4 disks) works perfectly fine there.
