Here is what it look like for me using AutoCAD 2009 and Windows Vista.
Can you see the windows title text?
Can you see the InfoCenter Search text in below?
When maximized I can see it or if the background is darker.
AutoCAD 2008 was much better as you can see.
How will AutoCAD 2010 look like? Invisible? Hope not.Here is a comment I got by email: "It doesn't change even you do change the window settings! Every new version of AutoCad gets worse!!!!!!!!!!!!"
