Flash on return to layered menu (DVD SP)

I'm using a layered PSD for a menu BG, with white text and gray text. I'd like the gray text as the normal and selected state, with the white text as the activated state. It works fine, except once the program is done, upon return to the menu, I see a flash of the white text before it reverts to the gray (normal state).

How can I avoid this flash?

(The white layer is above the gray layer in the PSD, but the white is deselected in the DVDSP menu's "general" tab.) I'm using DVDsp 4.2.1.)
