I am also using Reader 9.5.0 and its working perfectly fine for me.
What is the screen resolution of your machine as that might be causing this issue.
I usually work with a resolution of 1280x1024 as anything below it makes the display hard to read.
I noticed that the issue doesn't happen at certain lower resolutions such as 1280x800.
I also found that one way to restore the messed up title and scroll bars is to just hover the mouse over the top right corner of the Reader window.
I'm experiencing the same issue, but it usually happens when I drag an Acrobat window to a second screen. I too have been able to sporadically get the title bar to reappear. But haven't found a consistent method for making it happen.
No other program has this problem, so I doubt it has anything to do with drivers, resolution, etc. Acrobat seems to be the problem.
I'm using Acrobat X with Windows 7 Pro 64-bit.
