every time I click on any element of the lyx-menu-bar (1.3.3 and 1.3.4) my computer starts whistling strangley (ibook os x 10.3). As soon as I get the mouse somewhere else and click again, this sound is gone.
So sorry for posting this non-existential problem. But although I'm very happy with lyx this is a bit concerning. Has anyone had the same problem or even the solution for it? Thanks in advance. peter
