I've just discovered two bugs on Mac -- one crashing, the other merely annoying.
First the annoying bug: Start LyX. Close all windows (either with the keyboard or the mouse). Now (with the keyboard) enter <Cmd>N. This should open a new document; instead sometimes -- not always, but regularly -- my computer gives me a warning beep, saying in effect that I can't do that. The same is true for <Cmd>O, <Cmd><Shift>N. The only way to do any of these things is to use the mouse. In trying to investigate this further to see what the exact conditions for the bug are, I ran into a crashing bug (again, it only happens sometimes but regularly): Close all windows. Open a window, close it; repeat until crash. Here's the backtrace: Program received signal EXC_BAD_ACCESS, Could not access memory.
