I am trying to deselect all zimlets for some users having speed issues with older machines. I can't seem to get them all to deselect. When I do that, save and exit, and then go back in, they are all turned on again. I can deselect all the way down to just one, and it saves properly. But if I deselect them all, then they all get turned back on. Is this a bug? I am using version 4.5.2.
