theme-selector!

[Saruman <saruman horizon com br>]

hi all, I'm new in the list...
I'm using redhat 7.3 with sawfish...
I have a problem with theme selector! 
I click on "Install new theme..." and choose the gtk theme .tar.gz, 
but don't show the new theme on the theme selector for change!!!!
somebody can help me?
thanks!
