Storage not displayed properly in "About this mac" section Please refer to the image to see how Storage is showing me the space division.



Its showing amount of space available correctly but the division below is incorrect as you can see it is showing 249.72 GB for Apps and I only have 249.78 GB total space.

What can I do to correct this?

Edit :

Hi guys, thanks to everyone who responded and provided there inputs to solve my problem, really appreciate it. I don't know how but the space division is showing correct division now (I guess) , here is the snapshot of what is currently displayed :



I am not sure how it got corrected, the only thing I did was restart and immediately there was no change, but then I had some work and came back to the macbook again and saw the above scenario. Still not sure what does other signify and I am pretty sure that the space allocated to apps is wrong, is there anywhere I can check other than storage about how much space is allocated to Apps?
I had a similar problem, and rebuilding my Spotlight index solved it for me.

Simply restarting my computer (a less time costly operation), has also worked in the past.
