I might be posting more in the near future, because we are really trying to take our CBTs to the next level.
I am having trouble if motion paths and fades being jumpy in preview mode. When I publish to SWF, they all function correctly. As you can see, having to publish to preview could get a little tedious.
F4/Preview project would probably do the same. You might try F12/Preview in browser. The problem there is it will build all the slides, not just the ones you want to see.
I'm sure there's a technical reason why it only works when viewed in the browser, but sorry I don't know. I've never seen it happen with anything I've worked on, maybe it's a hardware limitation?
It works with F12. However, it doesn't work with F4, F8 or F10. I'm using Captivate 5.0. I haven't tried 5.5 or a different machine yet.
As a workaround, I use a seperate 1-slide presentation to preview anything. If I want to preview, I copy and paste the slide from my master presentation to the demo presentation file.
If it bugs me enough, I'll try a different machine which has 5.5.
I created a new project with a single text box with a LeftToRight Ease motion path and fade in&out. It worked fine.
Either my current captivate file is corrupt, or there are too many things going on, making it jumpy.
