Why after pressing the “Stop download” button the progress indicators are showing the programm is still doing something?
The button “Stop” in the main toolbar pauses download only. The already downloaded pages are still processed until the processing queue is empty. This takes usually few additional seconds. Also, the “Stop” button in the main menu does not stop autogeneration of thumbnal images. To stop thumbnail images processing right-click on the “Contents” item and use the commands available from the menu item “Thumbnails for all”.
