Descriptive Problem Summary:
Currently it's not possible to use the mouse wheel to scroll in any built-in browser.
Ideally this situation would be resolved by shipping a different rendering engine with BYOND altogether, preferably Webkit as in my experience it's much more standards-oriented than other engines.
Is it possible to fix the underlying problem, or is it possible to ship a different rendering engine with your software?
There are no known workarounds for this issue, which is why I believe it should have a high priority -- there seems to be no way at all to get this to work at the moment and this is highly unnerving for those used to a mouse wheel (which IMHO is everyone post-1997).
