Accidental double click on update-notifier starts two instances (on vnc)

[bsh]

Binary package hint: update-notifier

Hello
I have experienced this many times: when the notification of updates appears on the taskbar/tray, I sometimes double-click it to open up the update manager (as in my experience, double clicking is the most frequent way of restoring windows minimized to the tray). It then starts two instances of update manager, which work in parallel, and one of them gives an error sooner or later, that files are locked etc. (obviously by the other instance).
This is not really a bug, maybe a cosmetic thing, but I think, the notifier should have something to prevent double clicking.

Ubuntu version affected: all, from 7.04 upwards
DE: XFCE 4.4 & 4.6, Gnome *all*

Thanks for your bugreport.

The code should not react to clicks if they are done within one second. Is that a particular slow machine? Or do you click slowly? I was not able to reproduce it here.

It's an Asus Eee Box B202, with intel Atom N270 @ 1.6GHz (mostly running at 800MHz idle). Surely, it's not the fastest supercomputer, but ain't that slow either.
I am not clicking slowly.
There's something I forgot to mention, don't know if that has anything to do with this: it's a headless machine, i am using it with VNC, but on a gigabit network. (I only mention this, because it seems to affect update manager. I reported another bug, where update manager was terribly slow on this same machine when using VNC, but speedy on the normal display. Maybe the slow refresh rate of a VNC screen affects som timers or screen events that are timed to refreshes or something. This other bug is now gone, seems to be fixed.)

Is this still an issue with the latest release, Oneiric? This should not happen anymore, as update-notifier is using indicators right now, so clicking the icon brings up the menu, and as far as I know it's not possible to activate a menuitem twice with a doubleclick.
