Hi Jan
Sorry to hear about your struggle.
I just tested in Macromedia Captivate 1 and as you indicated,
an audio clip recorded longer than the slide simply adjusts the
slide time to match the new recording.
I then bounced over to Adobe Captivate 3 and performed the
same test. I recorded audio on a slide that was twice the length of
the slide. Just as I saw in version1, the slide timing was simply
adjusted to match the recording duration.
I'm wondering if the following bits are nailing you. In
Captivate 1, we simply click Audio and Record. But Captivate 3
offers new ways of recording. For example, the method I used in my
test was to click Audio > Record > This Slide. I'm thinking
that if you instead used Audio > Record > Project or Audio
> Record > From this slide and you have the option
"Continuous Play" enabled, that Captivate simply records as much
audio as will fit on a slide, then places the next segment on the
following slide and so on.
Hopefully this helps... Rick
