I may be the only one in the world that ran into this problem but I thought it might be worth talking about. The "change G code" button would not open the edit window. Talked to Daniel at Tormach and he discovered a glitch that occures when running the program on Windows 7. The PCNC program calls for Notepad to open but Windows 7 doesn't allow the ANSI version of Notepad so no window is opened, Daniel found a quick fix if anyone is running into this probem. I won't go though the whole thing if no one else is having a problem, but let me know and I will post how to fix it.:wee:
