Datagrid Problem

I have a couple of strange things going on with datagrids.

In the Columns tab of the Inspector for a datagrid, I see custom property names instead of the normal labels next to fields/menus/checkboxes, eg "dgColumnIsVisible" instead of "Visible"  The inspector seems to be functioning normally other than that.

The other problem is happening on a datagrid which I have set up by script according to the instructions in Trevor's Datagrid Manual by copying it from the rev datagrid library and setting up a template for it.  That all seems to work fine.  When I try to put data into the datagrid by setting the dgText, my script stops executing at that instruction and no data is displayed in the datagrid.  I also see the following errors in the message box but I'm not sure exactly when they appeared:

91,0,1
673,0,0,button id 1005 of card id 1002 of stack "qddev Main"
90,4258,33

573,82,1

Any ideas on what might be causing this?
