-your form.backcolor=rgb(255,255,255) &&white
convert it to rgb(0,0,0) &&(black) to be some compatible as gif picture color

-add a timer to the stockent form (interval=2000,enabled=.f.)
-in form.init
this.left=-5000 &&send the form to invisible aera
this.timer1.enabled=.t. &&after 2s make the form in form visible area

in timer1.timer
thisform.left=0 &&as you set
this.enabled=.f. &&stop timer it made the job assigned.

even with compiling an exe there is no flash (even if there is one its out of visual form area).
