>>ThisForm.Release does not work from within an Init event. What I did when I wanted this to be the case was to set a variable that flagged whether the form should be released. Then in the Activate event you can put the ThisForm.Release within the If statement if the form should be released.

Agreed. but closing from Activate event is still reasonable as generic solution. Usually, form object is started by following:

IF Type("...oMyform")<>"O" and NOT IsNull(....oMyform)
 ...oMyForm.Show
ELSE
 ...oMyform=createobject("Myclass")
ENDIF

and as you see Activate event will always fire, but Init just in second case.
