What version of Flash Player do you have installed? If you
have 9.0.16.0, that could be the problem. I was running Flash
Player 9 and having problems publishing Captivate content embedded
into Breeze 5. They wouldn't play at all after publishing to Breeze
5. Like you, this problem didn't occure initially during
development.
I uninstalled Flash PLayer 9, installed the older version 8
and then I could publish Captivate content embedded in the Breeze
files.
This combination worked for us:
Breeze Presenter 5.1.269
Powerpoint version 2002 and 2003
Flash Player 8.0.22.0 and 8.0.24.0
If I switched back to Flash Player 9, the Captivate content
stopped working again.
