This is my first serious project. I prepared 50 slides into a slide show and added a music track of 4mins and 2 seconds without difficulty. After saving it and playing it back many times I decided to add another slide at the end, which was a copy of my opening slide. Although I adjusted the on screen times of the last 10/12 slides to give more than adequate time for this extra slide I can not get P2E to resynch to the end of slide 51. The slide No51 shows in the main selected slide list (on the right of the screen) and when I play the project the slide plays in its correct position at the end but the music finishes with slide 50 and 51 stays on screen until I escape out of it. I have attempted every possible combination I can think of to removing slides and repositioning them. I have unsynched the project and ticked/unticked the control radio button but with no success. If's as if P2E holds on to the first settings and will not reset to new conditions/settings. I have tried to resolve this problem in V4,V4.2 and V4.3 beta. I accept it must be something I am doing wrongly but I am blowed if I can resolve it, Can anyone Help! LisaMike
