RadUpload disappears in Firefox

[Quang]

Has anyone encountered any issues with the RadUpload control in Firefox 2.0?  When a user clicks on the Browser's refresh button, the RadUpload UI control disappears and writes html to the page. Thanks.

Hi Quang,

I was unable to reproduce this problem in a sample application and also just replied your ticket on this reported issue.
Are you also able to reproduce this in our online examples here: http://www.telerik.com/demos/aspnet/prometheus/Upload/Examples/UsingTargetFolder/DefaultCS.aspx ?
If the problem still persists, as requested in the ticket, we will need you to send us a sample app in your support ticket that reproduces this behaviour in Firefox.
Looking forward to hearing from you.

Good morning Ubong, thanks for the update. After hours of testing and re-testing, I found the source of the error.  It looks like the RadUpload control cannot function and co-exist when you implement the MaintainScrollPositionOnPostback property at the page, or web.config level.  After I removed the property, the RadUpload control properly rendered on the page.  I did noticed that the Skins from time-to-time would disappear.  I had to implement the Rad Ajax Css Style Manager to address this issue.
