Yes it does, thanks.
When you download files their thumbnails are not removed from the display. This is so you can see what you have downloaded.
Important: when you no longer need to see these files, from the program’s main menu select “Clear completed downloads”. Their thumbnails will no longer be displayed in the window.
To get the program to again show you what you can download from your memory card, right click on the memory card name under the Devices section and click rescan. I will need to add this feature to the documentation.
To change the program preferences about when to clear completed downloads, see this: Rapid Photo Downloader: Documentation
I will also need to update this documentation to clarify that the same behaviour applies when a download source is rescanned.
I hope that helps.
