does anyone ever get logged off of UM for no reason?

no it does. i mean, i just leave it on when i'm at work, and once in a while when i come back, im not logged in anymore. its so annoying.
 
Hm, under "Edit Options" I have all my cookie stuff and logged-in stuff turned on (and my computer does take cookies for every other site). Is there somewhere else to turn stay-logged-in "on"?
