Minor updates of the IM clients have been released. Bopup Messenger version 5.4.10 and Bopup Observer 4.3.10 are now available. These non-critical updates fix a playback of a sound file when a new message arrives. This error occurred only in non-english versions of the client software, i.e. in German, Spanish, French and Russian versions.
By the way, the new versions improve a user's usability and it is easy to show or hide the application to a System Tray area by clicking program's icon near the clock. Click once to show the messenger, click again to hide it.
As always you can download the software at www.blabsoft.com/downloads
