Window Activation
 -----------------

  Please note  that  the animation  screen has to be activated  before
middle or right mouse button clicks are recognized. However, the first
left mouse  button click on a non-active window will not only activate
it, but is also sent  to the window's message port.  This implies that
if you  have some objects selected, activate ASpringies' control panel
to  do some modifications  and then  try  to  reactivate the animation
window for e.g.  moving the objects, that left click will also trigger
a new selection.

  To avoid this, either  use the  <space> key to toggle windows, which
performs  an  automatic  activation  (recommended),  or  activate  the
animation  window with  a  <left alt>-<left-amiga> keystroke while the
pointer is over it. You may also use  the AutoActivate commodity which
came with your Workbench.
