Physics problem

I'm trying to turn of gravity and after one second to turn it on again, but nothing happens and the object (splat) still hovers in the air. When I disable first event, physics works. Am I doing something wrong? What's other way how to do that, would be good if there was set it movable/immovable at the runtime?

Also I got these check failures when saving the project.

.capx download

• now as I'm uploading the file, I noticed it has 8MB! I've wanted a ground texture so I just downloaded first pic from google which was 2000x2000px 1,5MB big file, I resized it in the program, still it looks like this is making problems? Is there a size limit or recommended size limit?
