Comment 2 for bug 506216

I have changed anything recently so that's not it. My guess is that it might be loading a bit later (or earlier) for you than it was previously (did something get added or removed from your session startup). It's better than it used to be about catching and adjusting for changes in WM, resolution, monitors but it's still not perfect and it sounds like a change was happening after shinyswitcher was loaded that it was not detecting.
