This is a long time problem.


App Store icon shows an update available.  Open App Store, click the updates button (that also shows update available), then nothing shows in the window.


Also - sometimes I will get the little Software Update Available pop-up (the genuine Apple one).  So I click for details and App Store opens to the updates page, shows the same icon with the indicator that there are updates available... but then shows "no updates available at this time".


What in the world is going on?


Every so often, instead of a blank window with "no updates available", it will show Twitter, but then says "installed"....


If I delete the Twitter app, then re-download it from the App Store, it will disappear from the updates list... at least for a while.
