It's not that hard to make my original idea to preserve form's settings. E.g. form would have a new property called cSetCursor (you can make this setting to be in your application object, but IMHO, form property would better serve). Now in your class DoubleClick and LostFocus you would just put

if thisform.cSetCursor='ON'
set cursor on
else
 set cursor off
endif

For this property in the property sheet assign =set('cursor') (note, the = is important). I usually use it for holding status bar settings. In my forms I like to set status bar on. In form's destroy I re-set it back.
