Search Newsgroups??

[RTH]

I apologize if this has already been brought up...
There is no button or tab to let me search for certain newsgroups:(
There are 4 "half-boxes" at the bottom right of the subscribe window. 
There is no text on any of them but I am able to click them (nothing 
happens though). Anyone else having this problem??
