That when you start azureus, 2 programs are starting. Azureus and it's lancher. But when you quit Azureus, the lancher stays open. To solve the problem, just open the Activity monitor when you quit azureus, and see all the processes. You will see that the Azureus lancher is still open and it consumes 400 mbytes of virtual memory! You can quit it without worry, though... Anyone else has observed this?
