wxMac: OS darkening of inactive windows

[Michael Stauffer]

wxMac 2.8.3
OS X 10.4.7

Hi,

I have some non-modal dialog windows that I keep up for the user and OSX
darkens/shades them out when they're not active. In some, I'd like them not
to be darkened cuz I'm showing information in some static text controls.
Does anyone know if there's a way to get the OS not to darken/shade
particular windows? 

Thanks,
Michael
