i got this now too but it stays off if you click it off and never comes back on even after reboot.
because i turned it off the other day and today it is still off it won't come back on. :(
my main system., xp pro sp3.

As an addendum to the bug, switching from library/playlist view to Now Playing disables track browser. Switching back to a library/playlist view causes the track browser to remain permanently disabled until you restart MM4.

I am unable to enable the Track Browser. Both the toolbar button and the View menu entry are grayed out when in the Music Collection or any other Collection or their subnodes. It is probably caused by this fix: http://www.ventismedia.com/mantis/view.php?id=7185

Tested on skinned/unskinned 1345 on XP.

Can anyone else reproduce (you might have to go to the Now Playing node first and then a Collection node)?

The "Show Track Browser" command isn't enabled in the new build regardless of the selected node (Music/Location/Album/etc). Related to disabling it for [url=http://www.ventismedia.com/mantis/view.php?id=5792]Now Playing[/url]?
