Oliver,

The problem is you are creating a private memvar in the method to hold the child form object reference. When the method ends, the memvar goes out of scope and takes the form away. In your architecture you could 1) make the child form Modal or 2 )use a property of the parent form to hold the child form reference: thisform.oChildForm = createobject(...)

Also you do not need the second READ EVENTS the first one executed is the only one that has any effect on the system.
