I have installed Usoft on a new computer with dos and windows NT. The first day all was fine. Now when it is fired up the screen goes blank instead of showing the u.bat start up screen. The program is running as I can get the machine to home and print the header, but no display. If I esc. the start screen it does return to a C: prompt. I have completely reloaded the software Dos 6.22, WindowsNT 4, and the latest Usoft version. Any ideas?
