There are bugs in the older Help Browser such that dynamic displays often 
don't work. (There were worst problems in Version 5.2 with some animations 
that were generated by package code.) In Version 6 the result is that 
Manipulate and Animate expressions sometimes (but not always) just don't 
operate, i.e., the controls don't work.

There are two fixes. One is to copy the output cell from the Help Browser 
window into a regular Mathematica notebook. Without any further evaluation 
it should then work properly. A second fix is to append CreateDialog@ to the 
Manipulate or Animate statement and evaluate. This brings it up in an 
outside window and again it will work properly.
