Are you checking the "Remember Me?" box? Also, I asked the multitasking question because I thought it was really a weird thing to say. Kind of like "I open DV and then I go juggle 5 objects, and when I come back I'm logged out". I'm assuming what you mean by "multitasking" is you go read another webpage, or you work in a program, but that isn't really multitasking, that's just stopping what you're doing so you can do something else.
