I think I was able to keep multiple libraries open at the same time and when I hovered over the library icon, I could pick an open library. This was helpful when I worked with photo libraries and my SD card when I worked with PhotoShop.

Now when I hover over the library icon, only the last library I opened shows. Can mulitple libraries stay opened at the same time so I can hover over the icon and click on an opened library? I don't recall changing any settings.

Thanks,
Mike
