Sorry, Bear, for taking so long to get back. Care-taking is a hard job.
Anyway, After I changed the base setting to decimal, Entered the value 64240, clicked okay, exited RegEdit, and rebooted, I went back to check it and it reads in the large white pane:
Reg- DWORD 0X000fafo (64240) I cliciked on it and it has changed back to hexadecimal with 64 in Value Data. Is this the way it should be?
