Hi Ken,

Thanks for your testing on this and for following up.  How strange - I totally 
wouldn't have expected a toolchain upgrade to have changed how quotes get 
handled.

It sounds like it will be difficult to change the quote behavior.  So, we'll 
work to get VCL updated to handle the new behavior.

Thanks,
Josh
