Desktop Pager - Window Box Still Appears Even Though Closed

[launchybugger]

I'm running Lubuntu 13.10 x86_64 on a Dell Inspiron N5010 15" laptop...

I've noticed this issue in other distros with LXDE, so it seems to be an issue across LXDE, not just in Lubuntu...

When you close a Window(s), the box that appears in the Desktop Pager, showing you a window, this will still remain there even though you close the window...

So if you are on another desktop, you have to go back to the desktop this window use to be on and it will then disappear, or you have to click the pager for it to get removed, I forget which one now...

I find this really anonying because sometimes you forget and think you still have an application open, that's still showing in the Desktop Pager, only to realize there isn't any...
