I think something broke with the most recent version of Hides. Now, some (not all) of the time, when I select a new app in the dock, instead of the current app hiding and the new one appearing, I see the desktop, with all apps hidden. I then have to click the app a second time to get it to come to the front. It definitely doesn't happen all the time, but often enough to be annoying. I don't see a pattern to why it does or doesn't happen, but I do think it is more likely when I haven't switched apps in awhile.
