I have an application that starts the default browser by using
Process.Start(URL).  The one time that I get a file not found
exception is when Firefox has crashed and comes up with the "Firefox -
Restore Previous Session" screen.

It does seem to start up but for some reason an exception is thrown
because the browser hasn't started.  

Does anyone know why I get the exception in this case?  I don't want
to just eat the exception because the thing I start isn't necessarily
a URL.  It could be any format that may not have a default
application.  In that case, I want to notify the user that there isn't
anything to handle it.

Thanks.
