Don't need to use bindevents here. Instead define a custom property in FormA -- call it oFormB and set value to NULL. Then in calling FormB from FormA use the following syntax:

DO FormB Name thisform.oFormB

Now in the Destroy event method for FormA put the following:

IF !ISNULL(thisform.oFormB)
  thisform.oFormB.Release()
ENDIF

In the Destroy event of FormB put the following (this is to reset the property if the user closes FormB):

thisform.oObject.oFormB = .NULL.

I have used this a number of places without problems.
