Here is the environment:
Windows 7 Premium Home Edition 64 bit. Service pack 1.
PM 4.6.9 (Also, 5.0, but that computer is not available to me right now, so I don't have the release number)
Browser: Chrome Version 36.0.1985.143 m
Adobe Flashplayer 14
Problem: Created a PM Slide Show with export command, but nothing displays; no titles, no image, no thumbnails. If an mp3 file was added it does start to play.
Export options selected:
PM SlideShow
Open in Browser
Image Title: {caption}
Plays automatically
Show Captions
Use Full Screen HTML
Show Thumbnail Title
Finally isolated the problem to two images in the slide deck. When they were removed, the export worked correctly. When either or both were included with any images that previously worked, the entire export would not work (black screen in browser). Both are attached.
