Help With Status Bar - Still Showing Load In Progress Even After Page Load

I'm having an issue with the status bar in Mozilla and Netscape showing that
it is still waiting on the page to load even after it is finished. This
problem does NOT occur with IE.

In summary, I am using a onLoad event in the BODY tag to communicate back to
another server each time a page finishes loading. I do this by using a "new
Image()" and setting the .src property to the server. The .src includes a
value in the querystring so I know what request it was that finished
loading.

The challenge here is that the status bar still shows "Transferring data
from www.mysite.com..." despite the image being loaded. It never clears and
leaves the user with the impression that there was a problem loading the
page. My web server logs at the mysite.com show that the browser does
indeed make a request for the image and I get the querystring just fine and
it returns a status of 200 so the image is being found and served ok.

I've tried everything I can think of to solve this and really could use your
help please. Bottom line is that if you use the "new Image" statment from
within the OnLoad event of the Body tag, Netscape and Mozilla never seem to
update the status bar to show "Done" despite it succesfully loading the
image.

Here is a simply snippet you can use to easily reproduce this issue:
