I have a Silverlight 4 application that benefits greatly from having native mouse wheel support for a number of controls. The page that hosts the application has a HTML driven drop-down menu that would normally overlay the Silverlight control.
In IE, I have to enable windowless mode to allow the overlay menu to work correctly (Firefox 3.6 works normally without it). However, enabling windowless mode prevents Firefox from supporting mouse wheel events without additional coding around the HTML DOM bridge.
Is there any way I can tell which browsers will require windowless and which will work without it? Ideally, I'd like to use the HttpBrowserCapabilities information to decide whether or not to set the property to true, rather than hardcoding a list of 'supported' browsers.
