Hi...

I solved the mouse-problem by drawing the mouse on bmp2 and then blitting
bmp2 to the screen. That solved the flickering-problem.

I don't see how? Can't you post some pseudo-examples? ;o)

I was thinking of structuring it in a new way - as follows:
(still with a timer interrupt, increasing a global long-value, gameCounter)

while ( playing )
{
  show_mouse(NULL);
  blit(page1, page2, 0, 0, 0, 0, 320, 200);

  moveShip(page2);
  moveStars(page2);

  show_mouse(page2);
  blit(page2, screen, 0, 0, 0, 0, 320, 200);

  if ( (mouse_b & 1) )
  {
  }
  else if ( keypressed() )
  {
  }
}

void moveShip(BITMAP *bmp)
{
   static int gct = gameCounter;

   ship.putSprite( x, y, bmp );

   if ( (gameCounter - gct) >= 20 )    /* 20 => The "speed" of which the
ship moves */
  {
      /* Here goes: change x and y, so that the ship moves! */

      gct = gameCounter;
  }
}


Oh no! - I have been infected by a signature-virus!!! :o)
