Scott, I am sure you will be able to help with this one.
Latest versions of Mach have a htm file with the Gcode explanations. I find I look at it often.
This is the code behind the button, HtmlDialog( GetMainFolder()+"Mach3MillGcode.htm" )
It opens in what looks like a restricted Internet Explorer window. It is painfully small and not resizable.
My preferred browser is Firefox. Is there a call that will open it in my choice of browser window?
