[power-pro] Using ContextIf to hide a bar on a small window

[ebennetthill]

I use an Info bar that is positioned in the caption. I want to hide it when the 
window is too small for the information.

I tried *Format ContextIf ((win.width ("active"))>500) as the first command in 
the list, but nothing changed. I know that (win.width("active")) works, but 
ContextIf isn't using the number or I'm not using ContextIf correctly, or ... ?

What should I try to show a bar only when the window is above a certain width?

Thanks,
Ben
