[TR] why does the passenger window rock back and forth?

[<lstein6@gmail.com>]

1979 tr7, passenger window, when down, if you try and crank it up, tilts 
forward and jambs into front guide.   if i hold it at the bottom straight 
will go up.  noted that i can rock it back and foward a goodly amount. 
can't see where it is missing something?  it is held in place fine on the 
bottom bar that is attached to the crank(regulator?), not loose there. 
thanks!  larry
