Hello,

I recently updated to Calibre 5.17 from the 3.something I've used for a long time. I have had some issues with the viewer. I never had any issues before, so I can't say whether all of these "problems" are new. First, the viewer takes an inordinate amount time to load a book, and then, if it does load, it consumes over 300mb of RAM, even for a 150kb epub file. A second book take another 300+mb. And so on. Each book has four processes, the viewer plus three instances of C++ Application Development Framework. Second, and since I have plenty of RAM more important, the toolbar is gone. One can, for example, navigate through a book only one page at a time.

I'm using the 64bit version of Calibre for Windows 10.

Any help would be greatly appreciated.
