does it work if you use the default sound file. I seem to recall that the sound files used have to meet some weird requirement as to bit rate.

Thanks, Matt, for your answer! I probably have to explain this a little better. I have TB resting in the taskbar and see its icon. When I click on the icon, TB opens and I get sound and alert. My wish is to get the notifications already when TB is resting in the taskbar. I found the "Server Settings" section. Could it have something to do with it. What is meant by "Start up"? By PC or by TB? What means "Allow immediate server notifications when new messages arrive." Does TB have to be open or is it enough that it is resting in the taskbar? /hans peter
