Hi:

I have a page which has several iFrames.  In each iFrame, I have a refresh 
button to refresh the content of iFrame using the following JavaScript 
code:
<script>
iFrameID.location=url;
</script>

When I click the refresh button, every the other time, the IE status bar 
shows a slow growing blue progress bar hanging there for a very long time, 
just like the computer is trying to download large amount of contents 
through a slow connection.  From the content I know that the iFrame has 
finished the refresh action as soon as I click the refresh button.  I have 
no idea what the web page is doing after the refresh.  Let me emphasize 
that the progress bar hangs every the other time.

Does anybody know the possible cause of that behavior? and how to correct 
it?

I am using IE5.5  This is an Intranet application and we use IE only.

Thanks!
