Drive Letter for CD-ROM Won't Stay Changed

[EdS]

I have CD-R/W and DVD-R/W drives which I long ago assigned as drives K:
and L: (by using Computer Management > Disk Management > Change Drive
Letter and Path); they have had these assignments for the past couple
of years. Recently I noticed that one drive was assigned as G:, rather
than L:. I changed it back to L:, but the next time I booted up it was
back to G:. I've now changed it multiple times, but the asignment to L:
(or any other letter I try) only lasts until I reboot, when it goes
back to G: I also tried fixing this problem by editing the registry
(HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\DosDevices\G, but again it
reverted to G: after rebooting. (Note: My hard drive has 4 partitions,
C:, D:, E:, and F:, so G: is the first unassigned letter.)

There are reports that ZoneAlarm causes this effect.
Solution: Uninstall ZoneAlarm, boot, change the drive
letter, boot again and install ZoneAlarm again.
