KLWP goes blank in my home screen :(

In my phone, my setup (KLWP) oftenly goes blank after the phone unlock. it just showed blank black screen. it worked before I locked my phone. the only fix to this is to force stop the KLWP from the process screen, open the KLWP editor, save to apply my klwp setup, and fix the wallpaper thing. and not 5 minutes it happened again. Please help me in this. I LOVE KLWP :(
