Seamless RDP vs normal RDesktop (non-seamless)

Just a small note - If your Window Manager crashed (or accidentally closed) while you are working with some Windows XP program, then :

• If you were using seamlessrdp then you can not recover your session after you relogin (may be there is a way, but I don't know yet - appreciate any information if you know how to recover the hanging session)
  
• Else if you were using normal rdesktop session (without seamlessrdp) then you will be able to recover your windows XP session without any data lost
