I ran into what sounds like the same behaviour 2 or 3 days back, where breaking the program resulted in the mdi status display claiming it was reset to g54, but an MDI command did strange things requiring another break key hit. I found that altough the mdi status line said G54, I had to issue a g54, then a g5x to get back into the desired co-ord system and make mdi stuff work as one expects.. IMO, hitting the esc kay, or clicking stop, should NOT effect this as its completely by surprise that you get bit the 2nd time. Any change in the co-ord system should ONLY be accomplished by your code or by a specific entry from the MDI command line. I might add that entering a G55, without the G54 first, had no effect as the machine was still out in the north 40 someplace. I think thats best described as a PIMA. :[ My machines were all updated again today, so I haven't a clue if that behaviour still holds. When I encounter a problem and hit the esc key, I don't appreciate having the machines operating envelope jerked out from under me, hiding the clues I may need to fix my errant code. Thanks for mentioning it, John, I had already forgotten that 10 minutes of confusion. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
