to XSTREM: appreciate your 5 suggestions about BitComet. Here is the reply:
1. "Tracker Reture Zero Length Response". This is a bug in program processing tracker response. It will be fixed in next Beta version.
2. "Make the user-agent user-changeable". There will be an option in advanced settings in next version.
3. "BitComet does not fully respect the limiting of the connection". The actual download/upload rate is designed to approach the limit value. So I think some little error is acceptable.
4. "The CometBrowser does not shut down". This feature is originally for speed up next startup. It will be disabled in next Beta version.
5. "BitComet sends a COMPLETED-message even though it hasn't downloaded all files in the torrent." This is a bug and will be fixed in next Beta version.
Thank you again for your support to BitComet!
