Dear peterleinchen,
Some time ago I think the functionality of "download all details for visible caches" on the N900 changed to:
- All caches in view that were not updated recently: check their availability on the geocaching site. If necessary: archive or disable.

This is just my interpretation of what I saw happening in some cases. I must say I like it a lot. Although it would be perfect if the original function would work on top of it.

Thanks for the message, I will install the new version swiftly, before placing a new geocache this morning
