I still consider myself to be a novice as far as PTE is concerned but came across a problem in the last few days I wonder if other members have hit it. I wanted to start my sequence with four slides, they are all the same image but second has title on it and the third has a title and sub-title. I started with a fade in of just over 7 seconds on the first slide, a page effect left to right of about 5 seconds on the the next 2 and then a page effect right to left of about 8 secs for the fourth. Between each slide I only left about one tenth of a second. I then had about one tenth of second before the next slide and all others had an interval of about 2 seconds between finish of one effect and the start of the next. In the Customize Synchronisation box when I played this sequence, using the "Play" button, it worked perfectly it worked perfectly. However when I used the "Preview" button, the second slide came in on a left to right effect 3 times, the third and fourth never appeared and then all the other slides played as required. I found out that the only way to get the effect I wanted was to allow at least half a second between the end of one effect and the start of the next. Is this a restriction in PTE or am I missing something?
