#124 Window title bar buttons are transparent when add a bitbtn

[wniva]

The window title bar buttons (close, minimize, maximize) are transparent after add a bitbtn to the window or page.

I have located the problem in the buttons.inc.php in the function updateButtonTheme. When remove the line 159 and 160 (delete res.backgroundColor) then view the window title bar accurate. Another effect (when line removed) is a highlight on the bitbtn and title bar buttons on mouseover.

Unfortunately, I can not say what the function is needed (in the speedbutton the problem does not occur).
