Only downside is the lack of documentation...it may even be there, I've been too distracted building my slideshows!
I have recently 'Gone Pro' and while the cost may appear steep at first, you quickly become delighted with the value they provide.
The main issue I have is with the support forum. Author doesn't respond even after fair waiting and prompting, therefore use at your own risk.
Thank you for the review.
All is OK now. :)
