SWAG, I haven't tried this, so it may not work, but the form may think that it's already maximized; try changing to something like:

WITH thisform
   .lockscreen = .T.
   .WindowState = 0
   =DODEFAULT()
   .WindowState = 2
   .visible = .t.
   .lockscreen = .F.
ENDWITH

It may not be possible to trigger the Resize event within the Init, since it's prior to the Show(), but it's worth a try, since it will force VFP to cause the form to resize, not just minimize. Be aware that it might well call Resize twice, slowing down the display.
