On more than one occasion I have accidentally clicked on the geocache icon in a cache listing in Basecamp, which marks it as found. Is there any way to undo this? If I leave it as it is, my handheld will not show it as available when I download the caches in this list.
Unfortunately not. This is a known error that the BC team are aware of and a fix is promised, when I don't know. Falagar should be along later and he might know :confused:
