Rapid Photo Downloader not detecting new SD Card

When I switch card in my card reader I still see the photos from the original card in the preview. A rescan does not help. Apparently it’s reading out of a cache. How do I clear this? “Clear completed Downloads” also does not work.

Carefully follow every step here under Reporting Problems:

I should have added there is no need to look for duplicate reports, because there are none of that kind already reported.

Done. Thanks for your help, and for the program.

Yup, same here, RPD is no longer the default app for camera SD card. Started with upgrade to 0.9.20.
