Querying points on layer based on XY Table

[Lawrence Hartpence]

Hello,

I added a point layer which was based on an Access table with XY
coordinates.  The layer displays fine and labels fine, but I can't seem to
query it.  I tried using ItemQuery and just Query, but though it acts like
it selects a feature, it won't display any of the fields.

Is this a limitation in adding layers from a XY table?

Here is a link to the website where I am trying to do this.  The layer is
called Septic.  Clicking on the "I" next to the layer initiates the query mode.
