Digital Editions seems to stop responding to navigation keystrokes (arrow keys, page up, page down) at what appear to be random intervals.
Tabbing back and forth, have tried clicking(left and right) on every single pane / child control within the application to no avail. In the end, I have to restart the application. This is incredibly annoying. Keyboard support is disappointing.
Even using mouse, the controls don't behave like standard Windows controls, e.g. the scroll bar. Clicking on the inactive part of a scroll bar should produce the equivalent of a page-down, instead it scrolls down a single line incredibly slowly. Why isn't support for digital editions just integrated into the main Acrobat program? Digital editions seems like an unnecessary addition.
Also, are you aware that your program installs itself to the "Application Data" under the User account? I hope you have a good reason to do this, since last time I checked, this folder is only supposed to store *DATA*, not *EXECUTABLES*. You couldn't have possibly installed to the Adobe Folder under Program Files. That would make too much sense.
Design and implementation decisions that would make a graduate with a mail order degree in computer science scratch their head in confusion.
Sorry to be so brutal, but its these kind of things that should easily be caught in the Q&A phase of development.
Cordially yours,
