Cannot Save Macro Security Setting

[clundey]

Hello

I have a PC with Office 2003 installed and sp'ed currently. I'm logged
on as administrator. In Access, Tools-Macro-Security, I have changed
setting to Low. (So macros in application will execute). Then I get
warning about Sandbox mode, I select No do not block unsafe expressions
(yes doesn't seem to matter either) Exit out and start Access again.
The setting has reverted back to Medium. I've manually added the keys
in the registry
"HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Access\Security" and
"HKEY_LOCAL_MACHINE\Software\Microsoft\Office\11.0\Access\Security]

"Level"=dword:00000001" to no avail.

I've installed office 2003 on multiple machines and never not been able
to change this.

Any ideas are greatly appreciated! Thanks in advance.
