Elements 10.0.0.2607

The attached VBProj project has a build error:

Option Strict On disallows implicit conversions from ‘Double’ to ‘Integer’.

But when I convert it to Mercury, it compiles successfully without issue. In the Mercury project settings, it knows that Option Strict is On, so I’m not sure what is going on here. There isn’t a warning either. Strange.

Same behavior in Water.
