The attached cabinet is something I was mucking with to see if I could coax a corner cabinet into becoming an extended end cabinet. Apparently it didn't work, but the software still should not crash as soon as the Door Editor is opened.
By the way, I reduced the Right Front to 0\" using the associated up/down tabs. Putting in the number 0\" gives me the warning message that the software is not going to like that number.
This was a slight over sight with the spin buttons which will be fixed. The right or left front can not be less or the same as the material thickness. If you are using a ¾ material you can type in .755 and it will accept it.
