Re-opening 'switchboard' After Closing Crosstab Query?

I have a 'switchboard' form called Menu (not created by access wizard). One of the buttons down the navigation tree opens a crosstab query for the user to examine a data summary; but the 'Menu' form is still visible right in front of the query. Now, I could close the Menu form easily enough when the run query code is triggered, but that would leave the user loose in the database window when they eventually close the crosstab query window.

All that I have read on database navigation says that this is bad thing.

I can't place the crosstab query into a form or report because the column headings/fields don't appear when I try. (The field headings of the cross tab query are likely to change based on the underlying select query parameters so I can't hard-code the field names).

So, any thoughts on how to reactivate my Menu once the user closes the crosstab query or else puts the focus on the database window? (I achieve this using vba code in the on_close events of other forms and reports but I don't see an equivalent option for queries!)

Please note that I'm a vba newbie!

Thanks,
Craig
