Window position — Acrobat X, Mac OS X

A REALLY frustrating "feature" of Acrobat X on the Mac is the annoying inability of the program to maintain the window position set by the user. Every time the program completes a task, the Window position changes.
 
I have to use a macro to reposition the window constantly.
 
Adobe! Pay attention! It's 2011. The PROGRAM should remember where a user positions a window — you shouldn't require a user to manually move a window dozens of times a day!
 
And in the "Tell us about your software" below this box, why don't we have an option for the CURRENT release on the Mac? It's missing from the drop-down list! So, I've had to lie about the version I'm using (it's 10.1.0).
