Hello!
Thanks for the app. I have three comments to:
1. The app crashes fairly often - in all possible activities. The message "An Unhandled Exception has occurred: 0xC0000005".
2. In the version 1.5.0.2, there was a preview image in the Windows Explorer. That has pleased me. In the 1.5.0.4 version, there is no more preview image. Instead the affinity-symbol appears.
3. In the zoom level "Zoom to Fit" there are display errors (in the screenshot right below).
