Well, I can’t say I’m entirely shocked that others can’t reproduce this, but just to prove my sanity, here’s a screen shot.

Mac OS X Right menus behaving strangely

Actually getting that screen-shot turned out not to be quite as trivial as I initially expected, since it seems good old Apple-Shift-3 doesn’t capture the cursor (without which that screen shot is kinda meaningless). A quick search turned up the mostly useful Screenshot Hacks for Mac OS X page (I’d completely forgotten about grab.app), which was great until I found Grab didn’t show the cursor. Anyway, to cut to the chase, Grab.app has a preference which lets you choose the cursor to display in the screen shot, which defaults to none. No idea if it’s always been that way.

Anyway, for those who can’t reproduce this, one question. I can reliably drag from the left menus into the right, but never back (or from the right into the left). Do other people see the same, or is it a symptom of the same problem?

Update: Thanks to Simone Manganelli for a useful rundown of what sounds like the same bug. It doesn’t quite explain the inconsistency (i.e. I can sometimes drag from the time menu to the user one as in that screen-shot without a problem), but it sounds like those menus are generally problematic.
