Thanks Charles, I did that, unfortunately that did not find all the entries from the preferred lists. I found searching them independently did work. The problem with that solution of course is did it make the decisions I made first time around or quite different ones. I don't suppose I'll ever know and why did it not remember in the first place. After 8 hours of selecting species one at a time not to have them remembered undermines ones confidence; something I'm getting all too familiar with.

Hi Charles

To save me rummaging around, can you let me know a few examples of Lepidoptera species which don't match against the preferred list search option? I just picked a random sample, including latin and common names, and in my case they all matched to the entries in the LEPIDOPTERA list when I searched against All Preferred Lists.

In the latest version of Recorder, there is now a commit matches button so you can save the matches you have made so far. However, Tony is right in that the search operation is only within the current list option - there is no "search anything to find what I did before" feature. This is in theory what the All preferred lists option would give you, as long as it is working reliably. I can't see anything obviously wrong in the code either, so a few examples would be very useful.

By the way, the neccessity to search only within a selected list comes about because of taxon names having multiple meanings. E.g. is a redshank a bird or a plant - depends who you ask, hence the need to pick the list to search, and why any duplicates cannot come back as automatically matched.
