I branched your question to a new thread, because the other old thread was solved.
Which version are you using please? Some pauses are not visible in the timeline, as you can read in this blog post:
You can also check the actions On Enter for the slides: is that action set to Pause?
Drag&Drop slides are pausing, but that pause is not visible in the Timeline, only in the Timing Properties panel.
Interactive interactions are pausing as well, without showing the pausing point.
Please give some more details if you want help.
If this is a project that was created by virtue of importing from PowerPoint, look at the slides in PowerPoint. They are likely configured to pause until clicked. You will need to adjust them in PowerPoint and before you import into Captivate so they don't do that if this is the case.
