When I click on the volume slider of an app such as Totem or Rhythmbox, the multimedia keys on my keyboard cease to function until I click outside the app’s volume slider to deactivate it. This doesn’t involve just the keys I’ve mapped to control the volume but all the multimedia keys. Also, I have a feeling I’ve seen this with other active elements (i.e. not just the application volume sliders), but I can’t recall those specifics right now. I’ll add them to this report if I find them.
I’m running up-to-date Lucid (amd64).
I suspect this could be related to Bug #388547, but thought I’d report this as separate first and let wiser minds decide on whether this is a duplicate.
