[texhax] mathbb and a0poster class

[David Romano]

I have a student who is using the a0poster class.  The title, which uses 
\VeryHuge size font, doesn't show \mathbb{R} correctly:  The rest of the 
surrounding math text does display correctly
( $\mathcal{H}(\displaystyle\mathbb{R}^n)$)
but the size of \mathbb{R} is the smaller than the size of the 
superscript n.  Any help or suggestions would be welcome.

Thanks,
David Romano
