Many times I have the following problem. I create a new folder, but it doesn't appear in the Finder. Right now I have this problem with a folder created in Eclipse. After a while it appears, but I cannot tell when. I can see the folder in the terminal. A similar problem happens when I rename a folder or file. Then I have to move out of the parent folder, open another folder, go back, and most of the time it's there. (Finally the new folder appeared after creating another folder in the finder itself.)
I'm using 10.8 Mountain Lion now, but this is not a problem of this release. I have this problem for several years now.
Maybe I'm the only one with this problem? Is there a way to get this working normally?
