Hi,

This is probably because your child form is Modal. The parent code will wait at the Do Form statement, and only execute the Release once the child itself has been released.

You could set a flag when the user clicks the button on the parent, then in the UNLOAD method of the parent, call the child form.

i.e.
Parent.cmd_1.click

THISFORM.NextFormName = "son"
THISFORM.Release

Parent.Unload

IF NOT EMPTY( THIS.NextFormName)
DO FORM ( THIS.NextFormName)
ENDIF
