Edit function works not from progam window.  Pushing edit in program window or after learning mode LOAD/edit BUTTON.
Some loading windows blinks, but opens not editor.
Program list opens not in Notepad window.  Notepad.exe is in WIDOWS- folder and works properly alone.
Mach3 configuration general settings window the editors name is set to  c:/windows/Notepad.exe.
Who knows what´s the reason
