I experienced recently that I was unable to hit and click in flash based application using the mouse, which meant that I was forced to use the keyboard to navigate in all flash application - not a good user experience and very annoying. Adobe Flash does simply not register any mouse clicks (e.g. on YouTube, Google Analytics, etc.).
However I have researched on the bug, actually it was quite difficult to find anyone, who had experienced problem and reported it, also because the problem is hard to describe consistently. This fact was also clear, when I read the Ubuntu bug report.
The descriptions of the problem varies a lot: "Clicking on items in Flash player does nothing", "I Cannot Click On Flash In Ubuntu", "Flash does not register any clicks", and "flash does not recognise mouse clicks".
