Can I assume that, if the person downloads .NET 3.5 (full or client profile), my application can run on Windows XP, Vista and Windows 7?

Also, sometimes during startup, while my application is showing the splash screen, if the user clicks around or attempts to do something else - like return to another application while mine is loading, my application will fail to load and throw an error of some sort. Any ideas on what's happening or what I should do?

did you try .Sort() after writing and before reading the collection?

from the above, sortedlist works but it sorts the key ie. reg nos and not the marks.
