I'm curious for a better explanation (also). What was it that
you expected, armand? If the output of both projects was EXE, there
has to be time for Flash Player to close and reopen with the 2nd
(daisy-chained) project, and I assume this is what you are
describing, right?
On the other hand, if your output of both projects is SWF
(with HTML included), then there should not be a
"closing-then-re-opening" delay like you are describing.
Last thought: The "delay" the end user sees (assuming
"standalone" output) may be more or less, or even almost
unnoticeable, depending on the end-user's available resources in
terms of RAM, video capability, etc., etc. - this delay can also be
affected by the size of the projects, "size" meaning physical size
in pixels as well as other factors such as number of slides, number
and complexity of interactivity and so on, and so on, and so on.
Hope this helps.
