When this happens, can you see the project in the Navigator view (or in 
the Resources perspective)? The Package Explorer, by design, hides a lot 
of things; it is not a 1-to-1 representation of the file system but 
rather a logical view of Projects.
It's possible that you are just being confused because you're assuming 
that Package Explorer shows everything all the time.

Hope this helps,
Eric
