Hi Simon Do you have a custom preloader (i.e. splash screen), or are you using the default one? I've personally found that custom preloaders are sometimes problematic, with similar issues to what you're reporting. There seems to be a race condition, where if the Silverlight application downloads too quickly, the Silverlight runtime gets confused with what it should display (the preloader or the application), and nothing ends up loading. I'm interested in whether other people have experienced this, as I haven't seen it reported (I do discuss it in my book Pro Business Applications with Silverlight 4 though). But then again, sadly few Silverlight developers actually make the effort to create a custom preloader. I notice this issue primarily occurs on development PCs, where the application download generally does happen fast. So if you do have a custom preloader, try disabling it and see if that solves your problem.
