John,

If you want the other object to become a contained member object of the form use the form.AddObject() method.

set classlib to myclasses additive
this.AddObject( "MyContractsLetters", "MyContractLetters" )
this.MyContractsLetters.umnb1()

When the form destructs the other object will also destruct. Or if you only need the object for a short time you can use the RemoveObject() method to get rid of it earlier.

If you use CreateObject() you are creating the object bound to a memvar that will go out of scope when the method ends and thus the object will destruct. You'd need to create a PUBLIC scope memvar to prevent that.
