can’t delete password protected entry

This morning, I did a test with password protected entry. I wrote a message and put a password and it worked fine. However, this was just a test. So I tried to delete the post… and it didn’t work. I clic on “delete” and the post seems to disappear. However, if I take a look at my blog, the post is still there. And after that, if I return to my “manage panel”, the post is not deleted. What’s going on?
