Ah, thanks a lot. I realized my fault that I failed to follow your
instruction when you first provided the solution. You wrote

but my elisp code adds ".bindnow" only when preview-latex tries to tweak
foreground color while adding "-dDELAYBIND" option always.

After I modified the code to supply "-dDELAYBIND" only when necessary,
the error disappeared. preview-latex works for both cases when it tries
to tweak foreground color and does not.

Thank you very much!
