I also noticed a couple of problems for some time, but was unsure of how to tell anyone.
1. I have changed the Default Destination for some of the built in Categories such as Music and software, however when the torrent tracker automatically detects that type, it does not set the directory properly. I have to reselect the type/category in the torrent download window to have it go to the desired folder.
2. Sometimes when I open Bitcomet, my list port is open and the light shows green, but other times it is yellow. This problem only occurs when I am at home behind my personal router. I have Upnp setup in the router & bitcomet. Should that not open the listen port automatically?
P.S. I do enjoy using bitcomet very much and have for some time. Thank you for all of your hard work with this product.
