Same problem here also. It happens almost everytime I burn a disc. Usually I can open the tray but I cannot close the programm after that. It just freezes. Cannot even be closed by the Taskmanager (CTRL+ALT+DEL). I have to hard reset the computer. Annoying, really. I am just going through the forum waiting for a solution to be found. It's a pity as I liked CDBurnerXP but meanwhile I stopped using it. PS: WinXP SP3, BitDefender antivirus 2008, Outpost firewall 3.51. Very stable PC, no errors in the event viewer, never freezes, never BSOD, etc.
