Hi there
I'm getting this error back from various users of my app (I"ve not
seen it myself)

The class which is having the problem is this one:
public class UploadStatusViewController : UIViewController
{
public UploadStatusViewController (RectangleF bounds, int
lines) : base()
{
etc - it only has one constructor at this level.
I've not done an (IntPtr) constructor for it, so I assumed it would
take UIViewController's one.... Bug, or my problem?
Thanks
Nic
