Is it possible to resize an FX plugin window?

I'm in the process of demoing some Waves plugins. Already jumped through the hoops of getting them to show up in SAWStudio (shell2vst, etc...); but on one plugin, the Dorrough Level Meter, when I switch to a horizontal meter, the window stays the same size and shape, and all of the right channel meter and a bit of the left get chopped off.

Thoughts?
