i know this is not the solution to your problem, but it might help:

CLEAR

FOR i=1 TO _SCREEN.FORMCOUNT
	?_SCREEN.FORMS[i].NAME + " - " + _SCREEN.FORMS[i].CAPTION
	* *** _PARENTCLASSBROWSER
	* *** FORM1
	* *** CLASSBROWSER1
	IF UPPER(_SCREEN.FORMS[i].NAME) = "_PARENTCLASSBROWSER"
		*_SCREEN.FORMS[i].RELEASE()
	ENDIF
ENDFOR
