I recently downloaded the latest version of Mach3, R3.043.  When I start the program my keyboard JOG keys do nothing.  I have the program installed on two different computers and get the same reactions on both.
I open the Jog Control with the Tab Key.  I then click on Jog Mode and the CONT Indicator turns Yellow.  Now the Keyboard JOG keys work, but there is still a problem.  The Y & Z directions move just great.  The X direction keys only move the axis a small amount with each key press.
What can I do to make the CONT always selected?  What do I need to do to get the X JOG axis to work continuously?
Second question.
I load in a batch of GCode.  I maka a change in the GCode and then do a Regen Toolpath.   All looks well on the "Program Run" and "Tool Path" screens.  The "MDI" screen does not follow along.  To put it another way, when I modify the GCode on the "Program Run" page any changes made never show up on the "MDI" page.  The only way that I can see the changes there to the GCode is to shut down the program and reload the modified GCode.  Then it recognizes the changes.
Hope that all makes sense!
