I’m using HAMRS logger for Windows and really really like it! However, when I get over 100 contacts in a single log the program slows to a crawl. You enter a callsign and it then blanks it out requiring reentry. Also, the lookups become very slow too.
If I keep it around 100 things go a lot smoother…Hopefully you will address this issue before long.
(PS: this is on a fast laptop with plenty of SSD space.)
