Advance Mame Video Mode Menu

When playing a game in Advmame, if I click the Tab key, and open the video modes menu, I get a list that looks something like this:

Auto
224s  1.0
224s  1.0
224s  1.0
228s  1.0
etc

In other words, it only shows me the Height for each video mode. I noticed a screen shot on the Purple Mame web site (here http://members.cox.net/mame1/images/advm2.gif) that shows both Width and Height in the Advmame video mode menu.

Anybody know how to make both width and height show up (like the image on the Purple Mame site)?
