Errors in software simulation occur when pasting recording into larger scale program

Thank you so much for pointing me to your blog. I'm not sure what you've posted there applies to my problem. I've captured the software demo in the proper size for the space between the elements of the company's formatted background slides. So the background slide is 1024 X 768. The space for the software demo is 870 X 631. My problem is that elements of the captured demo appear in the wrong place when I paste the recorded demo 870 X 631 demo into the 1024 X 768 slides. So typing in fields that I've captured shows up above and to the left of the field in which the typing takes place. Once the typing is finished, the typed content appears correctly in the field. Similarly, when the demo creator clicks on a button, the button moves up and two the left.

At this point I created a PNG master slide at 1024 X 768 with a blank 870X631 space and applied it to all the slides in the program that had demo content, but the same problem persists.

So, perhaps I don't understand the workflow.

Should I create a wholly new Captivate file with just that new background and paste the demo 870 X 631 content into it?

Or should I be capturing the demo content at 1024 X 768 and following your re-scaling instructions. Any insight you can provide will be greatly appreciated.
