Hum, on hindsight, the extract parameter isn’t supported for p3d files, since they don’t have an extract directory in the same sense that packages do. This has been a bit of a problem with other kinds of p3d features that would be nice to extract, like dll’s and the such.
Hm. Well, in the meantime, there exists a workaround: you have to put some or all of your application in a package, and then reference the package with a p3d file. I realize this is a terribly clumsy workaround if all you want to do is change the mouse cursor; my apologies.
