I imported some ADIF records where the call and other info was in lower case. At import CQRLOGGER did not convert to upper and the calls were entered as lower case. I later went into these records to edit, and the conversion happened automatically, however the editing window apparently searches the log based on what the starting record was. Ie the edit window did not show earlier/later contacts with same station as it seems the search function distinguishes between upper/lower characters.
Not a big deal, just an observation.
