The tiles for the JOSM download dialog window can be deleted by using the "delete" button in the "*Mapnik*" [the "*Mapnik*"](https://josm.openstreetmap.de/ticket/17054) line (needs restarting afterwards). Technical details (and the hard way of deletion): The tiles are saved in `~/.cache/JOSM/tiles`. For me exactly in the files `TMS_BLOCK_v2.data` and `TMS_BLOCK_v2.key` (stored with the key "Mapnik" if I see correctly). Deletion of the whole directory or just both files results in JOSM downloading the tiles when opening the download dialog. Tested with version 14460 on Linux.
