Project upgrade CP5 to CP6, mouse jitter/undefined motion with HTML5 output

I have some current content that was created using Captivate 5 that is basic system demonstration with some simple interactions, clickboxes and buttons. When I open in CP6, it previews fine, publishes to swf good, but when I publish to HTML5, the mouse jitters and has an undefined motion, then moves back to the origination point. This is particularly obvious when there is no motion set for the mouse.

Also, the mouse is always on the top layer, even when I want something over it. This is less important than the mouse jitter and undefined motion, but would be nice to have a fix.

I am using Captivate 6 on Windows 7 Professional.

I have tried the following to resolve.

1. Saved as the newer version of Captivate prior to publishing
2. Shifting the timing of the mouse, saving, then shifting back, saving, then publishing
3. Blank project:
   • Exported backgrounds from original
   • Created new blank project the same size as original
   • Imported the backgrounds from the original
   • Added the mouse on each slide

Item 3 fixed the mouse jitter and undefined motion, but still always layered on the top layer. I would move forward with item 3, but I have several projects that need to be in HTML5 format, therefore I need a better solution.

Thanks for any help!
