Pro theme and Pharo 1.2 for Search & Replace

Hi. I noticed few differences with the Pro theme in Pharo 1.2

When I set the Pro theme, all the buttons of the current opened windows look ugly and with a white border. If I close the windows and then open them again, they are just fine.

However, I still find places where they are wrong, for example, with the find and replace.

Look the attached screenshot.

On the right you see a OB popup and it is correct. See the button "Ok". However, in the search andreplace popup (on the left), the buttons are ugly.

Do you know what can be happening?  is this a problem of the theme? or the find & replace popup?

Thanks
