TextCtrl.SetBackgroundColour() not working?

[Ed Leafe]

	I've noticed that SetBackgroundColour() doesn't seem to have any  
effect on a TextCtrl. In my app, if I want to flag a bad value with a  
red background, I use the code:

txt.SetBackgroundColour((255, 0, 0))
txt.Refresh()

... but nothing changes. Is changing the background not supported for  
text controls?
