Thank you for the reply.
I just thought the same than you, I checked all what was possible to check but I definitively don't have any link to this drive.
Neither in the history nor in any another tab settings.
I deactivated all aliases, all search folders, ... no way, the bug just happens every time:
open farr for a search -> ok
insert a disk (some burning operations) and remove it
open farr for a search -> error messages
So I think it's more complicated than just patch the history section, it's deeper than that.
Thank you for reading and by the way thank you for this (almost) killer-app.
