Gianfranco hi, 7.4.23 Manager does have a few bugs, such as not updating Task/Project panels properly. These bugs were found when 7.4 was still in alpha testing.
The worst GUI bugs were fixed around 7.4.39-41. It would be nice if you could arrange so that a newer version of BOINC is automatically available. Even the last 7.4 version would do. If Debian policies prevent that then at least please add the latest version to backports. In BOINC forums Ubuntu/Mint users are often told to install newer BOINC from your PPA but can't do that with Debian :/ Thanks, Juha
