HTML5 export broken in 9.0.0-dp-6?

[Terry Judd]

 Is it just me or is HTML5 export not working in 9.0.0-dp-6? A stack that worked in 8.1.2 just a few minutes ago now throws an exception...

To use dlopen, you need to use Emscripten's linking support, see https://github.com/kripken/emscripten/wiki/Linking

...and I seem to get the same thing event with a brand new stack just containing a single button. In the past I only saw this error when I accidently included something in the stack that it didn’t like (like a widget or a substack). Any ideas?

Regards,

Terry...
