Public bug reported: This has happened only once to me. I guess it's random.
I had Thunderbird open and maximixed. I moved the cursor to the left of the screen; the dock or panel with application icons appeared. I clicked on some icons, but the clicks somehow "went through" and reached Thunderbird behind it, having no effect on the dock. I switched focus forth and back to different windows and tried again and the issue persisted. Then I unmaximized and remaximized thunderbird and the issue disappeared (not sure whether I had to do it twice, though). When I had open Thunderbird, the system was a bit slow due to high RAM usage and paging (but when I observed the issue it wasn't any more), so it may be a timing issue where the order in which some things are done is not guaranteed but is usually right (which doesn't make it less of a bug). Note this is not a minor issue (though one that apparently manifests itself with a very small probability). Guaranteeing 100% you-click-on- what-you-see is absolutely critical.
