I was having an annoying problem on my MBP (10.8.5) where the cursor kept changing to the text-input bar in some areas of the screen, regardless of what application was in the front. I had a bunch of stuff open, and couldn't figure out what was doing it, so I chalked it up to an OS glitch and ignored it.
Then the same thing happened with a + cursor on my 10.9 iMac, and I started digging. Turns out that if I had a PDF open in Safari using the Adobe Reader plugin, its cursor changes (text input bar, target +, etc) were "falling through" to the front of the window stack, regardless of how far back the window with the PDF was. This doesn't happen immediately, but obviously happened on two of my Macs, on both 10.8 and 10.9. The Safari window with the PDF was sitting open in the background for a while (a few days) so it may take a while to kick in, whatever is causing it.
I'd nailed down a problem previously where the cursor would "twitch" about an inch or so to the side (which I replicated on about ten different Macs at home, work, and Client machines running 10.6 through 10.8) that turned out to be caused by any of several versions of Adobe Reader or Acrobat Pro, and I'm assuming this is directly related. (Interestingly--and somewhat ironically--while opening Adobe Reader's prefs would reliably trigger the cursor-twitch bug before, it isn't happening on 10.9 and Reader 11.0.4, so one or the other may have fixed or at least improved it.)
I'm curious if anyone else has seen this behavior before? I'm surprised, given that I managed to trigger it twice on two different computers, that I couldn't Google up any reference to it, but I might just be using the wrong terms.
In any case, further evidence of just how broken Adobe's software is these days. The fix, of course, is to let the native PDF viewer handle PDFs in Safari.
