Can't save modified macro security setting except through Group Policy

[lupidus]

I'm unable to modify and save Access 2003 SP 2 macro security settings beyond medium/default except through Local Group Policy (via the office11.adm here

http://office.microsoft.com/en-us/assistance/HA011513711033.aspx).

The options aren't grayed out in Access - they just don't save (after closing/reopening the app)

I've run resultant set of policy (RSoP) and there's no domain policies overwriting.

Would Jet 4.0 SP8 and/or sandbox mode be causing issues?

Thanks
