I'm having exactly the same problem.
MacBook Pro Retina, Mid 2012
OS X 10.8.3
QuickTime Player 10.2
Tried reinstalling QuickTime Player from the Mountain Lion install app; no luck.

Same problem here for a long time. Ridiculous bug. Here's how I finally got it to work!
If you don't have the QuickTime X under System Preferences, you can download it here: http://download.cnet.com/Quicktime-X-Preferences/3000-20429_4-10967183.html
On QuickTime Player X Preferences, enable "Rounded Corners"
That fixed everything for me. Everything is clickable, drop-down menus are actually accessible again. Classic Mac OS rounded corners for the win, I guess...

I couldn't install the control panel because of my Mountain Lion security setting, but I was able to use the following preference setting in Terminal which I found on MacRumors:
defaults write com.apple.QuickTimePlayerX MGCinematicWindowDebugForceNoRoundedCorners 0
(alll as one line/command)
It doesn't seem to have any affect on window appearance, but it does make the record button clickable (as well as making the player window movable).
