Photodex ProShow Gold, one of the most useful slide show creation programs we've seen for the Windows platform, has been updated to v2.5.
Changes include a new Light Box view that enables more slides to be displayed at once during the preparation of a show, support for QuickTime movies within a show, a function to collect all show elements to a single location, improved audio syncing, unlimited undo/redo and more.
A complete list of changes is here. ProShow Gold 2.5 is US$69.95 (electronic download version), or US$44.95 (electronic download version) to upgrade from a previous release. A fully-functioning 15-day trial version is also available.
