the install-line should jump to the correct version after update (again)
within the app detail view the line "installed" does not automatically jump to the correct entry after an update any more (although the version number in the header gets updated correctly). you have to leave the detail view and open it again to see the line at the correct entry.
i noticed it in version 1.2 and i'm not sure if it was already the behavior in 1.2-rc1, but i'm 100% sure it was not the case in 1.2-betaX.
