Hi Andreas,

There seems to be something wrong with MoveDisplay() on OS4. This code works as expected:

WaitLeftMouse()
For x=1 To 15
	Wait(10)
	MoveDisplay(#CENTER+x, #CENTER)
Next
For x=14 To 0 Step -1
	Wait(10)
	MoveDisplay(#CENTER+x, #CENTER)
Next

However, if I remove the Wait() in each loop, the display does not return to the center of the screen (it just keeps going to the right). This problem shows up on my OS4 machine; but I tried compiling it for Windows, and it worked correctly---with or without the Wait().

That's not a bug in Hollywood but just the way Intuition works on all AmigaOS implementations. It's an asynchronous window manager design so position change requests are not done immediately but deferred until the next input event. I'd guess that the old request is just deleted then if there's already a newer one or it is executed but you don't notice it because refresh is not done before all requests have been handled.
