Hi everybody!
I set a background for my figure, but now, when I add a panel, I only see the title, the rest of the panel is transparent, and I see my background... There's something I can do?? I tried using "Bring to front" and "Send to back", no results!

That is the behavior you would get if the BackgroundColor property of the uipanel is 'none' . Perhaps you set the color explicitly in your uipanel() call? Or perhaps you have set the root property DefaultUipanelBackgroundColor that is set to 'none' ?
get(0,'DefaultUipanelBackgroundColor')

Windows 7, Matlab 7.12.0 (R2011a), and the get returns me "painters"

H = uipanel(..)
What does:
get(H,'backgroundcolor')
return?

I am not able to replicate this. If you run my three line of code above, the uipanel is on top of the blank white axes in a new figure?

Perhaps it's your choice of liquor. I think the renderers prefer gin.

Nothing to do...
I can't understand why when I don't see my background, everything it's ok, but when I use it, panels became transparent...
This is it:
With the BG
Without the BG
What's the problem???!

Nope.. It's the same...
There's a way to bring to front my panel using code?

What happens if you try
opengl hardware
set(gcf,'Renderer', 'OpenGL')
drawnow
and look at the output, and if that did not work,
opengl software
set(gcf,'Renderer', 'OpenGL')
drawnow
Your panel probably _is_ at the front from what you have described. (Your test works as expected for Sean and I.)
