After editing a cabinet on this job and returning to the main area ecabinets just shut down like turning off a light switch. What gives, it did not give me an error message or warning or anything. This happened twice on the same job at the same point.
I am editing the middle cabinet to fit between the upper and lower, that is when I loose the program.
I have found that it is when I change the width of the left and/or right stiles is when it shuts down. I thought it might be because I have edited and applied constraints to the mid rail. When I removed the editing of the mid rail it still shuts down.
EDIT
I had to remove the offending rail and add it back with no editing in order to be able to save the cabinet. I think I have it working now.
