When logging off or restarting, right before the system reboots, Windows gives me a Program Not Responding message for these programs or processes: UD.EXE, DEVLDR and EXPLORER.EXE. UD is a program that's in my startup folder, i want to keep it there. Don't know what DEVLDR is or does, and EXPLORER.EXE is the Windows shell. Anyways, these messages pop up and I can click End Task or Cancel and they will go away, or simply ignore them and Windows will take care of itself and simply reboot/logoff, whatever I asked it to do. Anyone know why this happens and how it can be fixed?
