safari autofill issue

hi.

I'm having a problem with safari. Everytime my mac goes to sleep, next time I wake it up, autofill options in safari are unchecked. I don't know why is it like that. Does anybody else have same issue?

Just so happens i read another thread and this link is courtesy of vansmith.
