hay David,

When you define the Window, use the NAME oWindow clause to create a object reference to the window. This object is of the FORM baseclass. In the FORM class is a property called AlwaysOnTop. Set this propoerty to true (.T.). Here a sample:

DEFINE WINDOW test NAME otest FROM 0,0 TO 100,100
otest.AlwaysOnTop=.t.
ACTIVATE WINDOW test
