[QUOTE=Kyatric] Uncompressing your zip and opening the caproj raised a check failure that I ignored, and previewing the project launched JS assertion in my FF.
Last time I saw this, the person who was sharing the project had saved different projects under the same .caproj name in the same folder.
This is not really good practice.
As this is only a starting project, i'd recommand you to make a new project, and save as single file for a while (capx).
You can find more about it in the manual entry about saving and sharing projects
and also have a look at the best practices
For now, start over from scratch, add a (little) sprite and set solid behavior to it.
It should stay in position and all should work well.example capx
(make sure to check the example capx in the folder C2\examples too)

Interesting. I started over with a single .capx file, as you suggested, and now it all seems to work flawlessly. C2 did tell me the sprite was very large and may not be supported on all systems when I imported it, but that didn't stop it from working. Thanks for the help.
