I know that there has been a post like this, but it didn`t help me! So I have a problem with my LW, when I start it it disaperas after a couple of seconds, when I point at the tray icon then the icon disapears. I`we already deleted my preferences folder and done everything you usualy say when this happens, but it still doesn`t work, my Java is fine. I just can`t do one thing, ther was this tip before runing LW press on the icon with right mouse button, then Run as, and click on the administrator user, well it says that the password is wrong, but I`m an administrator on my PC and my Dad`s user is an administrator too, but he hasn`t got a password, so what could be the password for that? (I tried mine, it didn`t work!)
