Math & Science ⇒ beamer poster display equation: \int too small

[bmosov01]

I'm currently trying to make a conference poster using the beamerposter package. Everything seems to be working great, except the math operators are too small. I've tried everything I can think of, and have searched several sites for a solution, to no avail. Here are the things I thought should have worked:

-- using the \big,\Big, etc. commands as in \big{\int}. Apparently you can't use these on math objects such as integrals. All I got was an error.

-- using the \large, \Large, etc. commands as in \large{\int}. No effect at all, not even an error.

I need to keep my scaling at scale=0.9 (the option when invoking the beamerposter package), so that needs to stay the way it is. The poster needs to be 36"x36", so I included a couple extra lines in the beamerposter.sty file (lines 83-87) to specify the poster height and width. Perhaps when I did this it screwed up something with the vectorized font scaling? Perhaps I need to tweak something else in that same file?

One thing I did discover: commenting out all the lines under the "scalable vector fonts" comment in beamerposter.sty (lines 167-226) made the integral signs appropriately proportional, but screwed up the rest of the text scaling. If I were to print the poster like this, the text would be illegibly small (but integrals would be the right size!!). This is what leads me to believe that the math operators are not getting rescaled appropriately somehow.

Sorry for the long-winded explanation, but I wanted to be precise. A minimal working example is contained in the source files below (one .tex file and two .sty files that are identical to those I'm using for my actual poster). I know this is a very detailed and specific problem, but I would **really** appreciate an answer if anyone has one, as this poster needs to be done by noon Monday.

Thanks in advance for any help you can provide.

Try adding:

\usepackage{exscale}

right before \begin{document}

THANK YOU! I can't believe it was something as simple as that. Worked perfectly. Everything displays at the proper scale now provided I include that package after the \usetheme{confposter} call. You just saved me quite a bit of headache. Thanks again.

This is a little bit surprising since amsmath should do the same job as exscale.
