Have used NAV 2000 - 2003 and it the last one is going to run out in May. Despite all the criticisms NAV has never let me down so why not try out a beta version.
Powerless - When I followed your link it said that I should "be sure to follow the installation instructions in the readme file that accompanies the beta software." but there was no read me file saved to my disk. Any suggestions? (Do I uninstall previous versions etc?)
