For those of you that have experienced instability related
to memory usage while presenting, we apologize. We have just shipped a
significant update for Windows and Mac that addresses the memory usage issues. There
are a couple known issues which will be resolved next week.
Image Slideshow editor (Mac) - scrolling through the edit
preview loads the visible bitmaps into memory. The memory will not be freed
until you move on to the next service item. If you had a single image slideshow
with 100+ slides using high res images and you manually scrolled the edit view
down you could exhaust your available memory and crash the app. Moving on to
the next service item editor will free this memory. We hope to get a fix for
this issue out early next week.

Slide transitions performance (Windows and Mac) - The
foreground and background layers used in each slide are generated on demand and
destroyed once you move on to the next slide. This can result in a noticeable
lag when transitioning between slides. The next phase of this redesign (next
week) is to cache the generated slides to disk which will make transitioning even
heavily stylized slides snappy.
