I'm trying to simplify a presentation .fla file I inherited. I was able to
successfully build a slideshow that functions exactly as the original except
for one thing, there's a slight lag between slides. Each slide is a .swf file
so I can add fade-ins/outs as needed and include animated slides such as
converted .movs (next step is trying to figure this out in XML and adding a new
attribute but I need to get something simple working now). There are a couple
slides that build on as a reveal so the blink caused by the lag breaks the flow
of the presentation and is unacceptable. It's even worse when slides
transition to fade-outs and blink out then on and then fade out. Any
suggestions or is this simply not possible using XML or by loading external
files?

The .fla and .xml file can be found http://www.monderer.com/xml_slideshow.zip.
