Comment 8 for bug 1340179

Hello. I'm not sure if this is related, but when I launch calibre (Ubuntu 16.04) the calibre icon shows up in my launcher, however, the viewer icon also shows up and it seems that icon is what is actually associated with the running instance of calibre. I did move the viewer icon into /usr/share/pixmaps and edited /usr/share/ebook-viewer.desktop to use the viewer icon, but I'm still seeing the same behaviour (even after a restart). Right clicking on the calibre icon only give me the options: 'calibre' and 'lock to launcher'. Right clicking on the viewer icon give me the options to 'quit' or 'lock to launcher'. Strangely though, when right clicking on the viewer icon, I have an option for one of the last books I had open. I don't know why this would matter, but this behaviour started after I repositioned the viewer icon on my launcher while I had a book open. The book that was open at the time is the same one that is showing up in the context menu when I right click on it even after opening other books. I've installed calibre from the ubuntu repo through apt-get and have reinstalled, removed, purged, etc. several times and the behaviour remains. I'm at a bit of a loss and hope it's related in some way to this bug and will be fixed in the near future. In the mean time, if there's a work-around, I'm all ears. this doesn't really affect my ability to use calibre, but it's super frustrating. I've included a screenshot, though it may be of minimal help. You can see that there isn't any book open and the calibre icon (bottom left in launcher) doesn't have an indication next to it that it's running. You can also see the ebook viewer icon is active and shows my python book open, though it's not. If there's any info I can provide or changes someone would want me to try, I'd be happy to help. Thanks in advance for the help.

P.S. I apologize in advance for the giant screenshot.
