Yes, when this happens for me, it makes no sound and simply rollign my mouse wheel up and back down a few times on the patch number usually fixes it.  I have no clue why this happens and it is probably worthy of a bug report.  Just make sure you reproduce with 1.4.15 to make sure you aren't filing an already closed bug.

At the moment, I'm not - 0.4.1.5 Windows, 0.4.13 Ubuntu. But I had the
same problem with 0.4.14 Windows and 0.4.13 Windows. This suggests
there's something actually wrong.
