How to Place an Anchored Frame in Center of Multi-column Page?

[Mike Wickham]

Is there any way to place an anchored frame in the center of a multi-column 
page? I use the two-cell table method for placing graphics and captions. The 
graphic is in the top cell and the caption in the bottom cell. It works 
great in-column, but I'd like to place a 1-column wide graphic and caption 
in the middle of a two-column page, so that the anchored frame partially 
overlaps each of the two columns. And I want the text in each column to run 
around the anchored frame. Does anyone know a way to do this?

The closest I've been able to come is to draw a text box in the center of 
the page, and place the table inside. It looks great, and runaround works as 
desired, but since the text frame is disconnected from the main flow, the 
figure numbering doesn't increment properly.
