When reporting a bug, please try to provide as much information as possible. For example, you should provide your machine specifications (e.g. Processor, Operating System, Graphics Card, Memory, DirectX version). You might want to add these to your signature for convenience.
You should also try to provide a short example of the fault in action whenever you report a bug. This will enable other users to confirm the presence of the bug (or possibly fix your code!), and makes it much more likely that a fix can be provided in a timely manner.
