I am doing a systematic review and sorting thousands of references from an UNFILED group into YES, NO and MAYBE groups.
Just yesterday I was able to drag and drop a reference between groups - it would disappear from UNFILED and be moved to the YES/NO/MAYBE group it was dragged to.
Today when sorting, it is now copying each reference instead of moving it - meaning they are no longer disappearing from my UNFILED group folder. According to EndNote help and the internet, this is normal?
How can I go back to moving a reference with drag and drop, rather than copying it? It makes my work much easier and faster. Cutting and pasting is laborious and requires many clicks.
Thank you.
