I have just installed Firefox 4.01 on my Win7 x64 PC. The menu bar is selected to be always in view. I notice that the background color of the left part of the menu bar, where the text resides, carries an obviously lighter '''shade''' than the color of the right part of the menu bar, as the following pic shows: http://drkh.myweb.hinet.net/FireFox_menu_bar.jpg Is that normal? The default theme is in use and the "transparent glass" visual effect of Win7 is turned off (but the shade is still lighter even when transparent glass is turned on).
