I hope someone out there can help me with this one since I'm stumped!

I have an Excel form that I created that contains a number of checkboxes that uses select to choose options they want in a package.

These have been working fine until just recently. Now, when my Excel worksheet loads, I can see an outline of where each Checkbox should be and a red X flashes briefly and then they all disappear -- basically, they fail to load.

By clicking around, sometimes I can "catch" one and it will display, until I move out of the field, then it disappears again.

This same behavior appears in new worksheets as well as existing ones and occurs with text boxes, button boxes, and check boxes (basically anything you might add from the Controls Toolbar).

The other thing I noticed is that when I click the "Design Mode" icon, the label on the button changes from "Design Mode' to "Exit Design Mode", but it doesn't look to me like I'm really ever entering Design Mode -- I can't select objects, for example, the way I should be able to.

This behavior started occuring after I upgraded from Norton 2004 to 2005 -- so I don't know if that has anything to do with it. I don't think I've run any other updates recently, so I'm not sure what is going on.

Can anyone help?
