If you have a problem with blank screens coming up during the slide show, click on the left arrow and the right arrow a few times. This will usually give the slide show program a boot in the butt and it will usually start behaving. Once it has gone through the first rotation, all future shows should run with no problems. "Don't ask, Don't tell".....at least I won't tell because I don't have any idea why it does this!
Slide show time has been set at ten seconds. This may help.
