pre-loading items in Slide object

[David McFarlane]

Terhi,

Start by looking at the SlideSoundOut and SoundBuffer topics in the 
E-Basic Help facility.  Then look at the "Load Image Upon Mouse 
Click" example from the Samples area of the PST website, I think that 
will show the mechanics of how to access Slide sub-objects.  Then 
take it from there.

Stock reminder:  1) I do not work for PST.  2) PST's trained staff 
take any and all questions at 
http://support.pstnet.com/e%2Dprime/support/login.asp , and they 
strive to respond to all requests in 24-48 hours -- this is pretty 
much their substitute for proper documentation, so make full use of 
it.  3) In addition, PST offers several instructional videos on their 
YouTube channel (http://www.youtube.com/user/PSTNET ).  4) If you do 
get an answer from PST staff, please extend the courtesy of posting 
their reply back here for the sake of others.
