Thanks PHV,
I reviewed my sandbox setting in my registry (thanks to your link,) and it was set to 2. According to the link, you can set your sandbox to the following:
Setting Description
0 Sandbox mode is disabled at all times.
1 Sandbox mode is used for Access applications, but not for non-Access Applications.
2 Sandbox mode is used for non-Access applications, but not for Access Applications. This is the default value.
3 Sandbox mode is used at all times.
Mine is set to "2"! If I read it right, it shouldn't present the warning while in Access, right?
I'd rather not drop my security to "0". But I'll give it a try to see if the warnings discontinue.
