I'm in Linux Mint 14, Xfce.In Synaptic Manager I see these marks that seem to indicate an available upgrade, but there isn't any.Update manager finds nothing to upgrade.For other programs these marks are absent:Is there something amiss here?(Maybe related to the fact that I have upgraded Thunar as shown here which I guess upgraded Xfce too.)What are these marks?
Why do I see update-like marks in Synaptic Manager (Mint/Xfce) although there is no update available?

The package you selected is up-to-date, you can only do re-installation as the Synaptic Package Manager suggested.If your update manager is not showing any package to upgrade, try update the package cache, IIRC there's a Update button you can click on (or sudo apt-get update in CLI). If it still contains nothing, there's no package update available.
