vnc logs out user, i dont want

i have opensuse 12.2 (im going to change that to thumbleweed) 63 bit KDE.
i have set up a vnc server (using vncserver) and it works good.
but the problem is here: i log on to my user, open some apps (like ktorrent, i want to control it using web interface) but when i disconnect, all programs are closed (user logs out).
can i make vnc to keep my user logged on?

also i tried some searches for remote desktop (rdp protocol) but couldnt set it up. is there a nice way to set it up in opensuse?
thanQ
