I don't know if there is a "usual" length. I have left my default at 28, but that's my choice. >b. Is there a limit to the length of the score used? >i.e. does one design into 1000's of frames?

Wide score sprites (wider than 1000 frames or so) can be difficult to reposition in the score. One workaround is to shrink them (using the sprite tab of the PI), then move them, then grow them again. As this is an authoring-only performance problem that doesn't comes up too often, considering fixing it has been on the back burner for a while. 2. The appearance of the first frame of a Shockwave movie can be appreciably slowed down by large scores (thousands of frames and sprites). Since all score data must fully downloaded before a movie can start to run, if there are thousands of frames and/or hundreds of sprites per frame, this can cause a significant delay at the beginning of a Shockwave movie (there are Tech Notes at MACR about available workarounds). Note: all scripts and fonts must be fully downloaded prior to startup too, so many of these can also contribute to slower Shockwave startup. Projectors are not effected by these particular startup issues. hth -Buzz [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/LUJ/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]) Lingo-L is for learning and helping with programming Lingo.
