I'm running ThunderBird from my U3 drive (Sandisk Cruzer Titanium) and it often happens that moving from one message to another or opening an attachment takes seconds - the app looks like frozen... Do anybody have any idea what can be the broblem? Version is (I think) 220.127.116.11 - the one installed via U3.com. Size of the message box on the drive is over 100MB - can this cause the problems? I'm connecting it to USB2 port of course.
Thanks a lot
