Error C2259: 'juce::Typeface' under VS2012

Hi, 

Am trying to build a version of our plugin using VS2012.

We are getting a weird issue where by CustomTypeface implements Typefaces pure virtual functions in JUCE and it all looks fine, but VS2012 still is throwing a C2259 error. We don't inherit from custom typefaces anywhere in our own code and it works fine on xcode, have cut and pasted the compiler output below...

Gavin.

Trying to instantiate an Array<Typeface> maybe? That ain't gonna work!

HI Jules,

We do try and instantiate a CustomTypeface in the code, but thats it. 

Gavin.

No.. look at the error. It's telling you that it can't instantiate an Array class, because you're giving it a template param that isn't a copy-by-value type.
