Digital Editions does not seem to remember the size of its window from one session to the next. In other words, the first time I started DE, it was sized at about 70% of the total screen size in both directions. I like a larger window, so I sized it to the edges of the screen. I also reduced the size of the left pane, as this made the facing-page view close to as large as it could be. However, when I closed the application, and then opened it later, it was back to that 70% size.
I could not find any kind of setting or option that would change this behavior, though I find it stunning that such a basic usability consideration would be overlooked. It's very irritating to have to resize the window again every time I open the program. Is there something I'm missing?
