Is there an option for MD not to use a "skin". I quite liked how older versions looked, using system default colors and windows.
I tend to run my system in "classic" mode, no skins, frou frou eyecandy or themes.
It the older versions were snappy and I didn't have to see skinning being applied when starting/restoring the application.
You may want try to switch the View | Toolbar | Flat Buttons menu item.
Will it make the change you want?
