Thanks guys... I found the solution! Seems I had to separate the Image, from the ;Window code, and add a #VOID# instead:
;IMAGE
Graph1.png
8,196,32,32
;WINDOW-0
8,196,32,32
#VOID#
Graph_HrTemp.wpx
74,159,92,54
CHILD
Not sure why this made such a difference, but now have 7 "children" playing nicely....
