In that thread which you linked to, it sounds like the poster has simply discovered how TM is supposed to work. You open a Finder window then you Browse TimeMachine. He posted "This is where I found a workaround. While this volume window is in the foreground, I can use the Time Machine menu to successfully "Browse Time Machine Backups" or click the "Enter Time Machine" button. Suddenly, Time Machine's interface seems fully functional. From this point, I can browse to whatever files/folders I desire to recover." His so-called "volume window" is a Finder window, it's not a "workaround".
