Hello Peter, The "Permit control of show using keyboard" is on the main Tab and is marked. I tryed to use the mousebuttons on several possebilitys and none of them worked?! First with the left on previous and the right on next slide so that people will be able to pause the slideshow with the spacebar. Should it be something with the version it is made of (V5.00 beta 6) ? When I Update my version I have to remake it ALL over, ain't it? regards, Luc
