Here's something that baffles me - it's so easy to install Gnome 3 with "Gnome Extensions" on 12.04, why isn't it better known?  Do a google search "12.04 gnome 3", and follow the instructions to install Gnome 3.  Then add "extensions" from the Gnome extensions web site.  With Gnome extensions, you can get Gnome 3 to act like Gnome 2.  I also learned how to theme this whole mess (google changing themes Gnome 3) and now have three computers running 12.04 that operate far better than any previous Ubuntu versions.  Not sure why this isn't more well know....

Could be one of million things so I doubt this reply will be of any use.  Re-read all the setup instructions in the forums - that's the best place to post for help too.  The real reason I'm replying is to mention that using TightVNC/IPsound/Hamanch is a much better solution and easier to set up.  Get HRD running and talking to the radio then download and install TightVNC onto both computers.  Almost that simple.  In addition to being able to manipulate HRD, you can also control everything else on the remote computer.  Very handy.
