Win form application not updating label

I am currently writing an application in C# that processes some XML among other things. Some of the XML docs can be quite big so I added in a label to show the user that characters are still being processed and that the application is still running.

The actual XML building is being run in a different thread but the XMLInProg and charsProcessed are class variables which the main thread can see and use them to update the GUI.

For some strange reason, I can only get the status label to update whenever I get a messagebox to popup along with the update. Can anyone explain why?

Thanks.

This does not work...

while (XMLInProg)
        {
            status.Text = "Building XML... " + charsProcessed + " characters processed";
        }

But this will work

 while (XMLInProg)
        {
            MessageBox.Show("Works now");
            status.Text = "Building XML... " + charsProcessed + " characters processed";
        }

Call the refresh method on the label (within the loop):

status.Refresh()
