For whatever it is worth, I see some error messages when using morph including the “Dialog” error. I have also had it add it open with 5, 10 20 + morph command rows. Here is a pic of the area I am referring to. By the way, what is the correct term to use for this area?
Any way, I have not specifically tracked down the cause but I have narrowed it to the data in the field that is being morphed or being used to morph a different field. I think if the field contains option L character or cr() character it will cause anomalies and errors. With the cr() character, it seems to cause issues if it was imported from Pan 6.
I will try to get more specific next time I encounter the errors but for now maybe this info well help to track it down.
