I updated my thunderbird to 11.0.1, but right now after I minimized it to the system tray I can not show it again! what's wrong? Is it because the updating? when will you provide next version? P.S. my OS is ubuntu 11.01.

Questa recensione riguarda una versione precedente (0.4.1.1-signed) del componente aggiuntivo.
