Created Unassigned: AsyncFileUpload mozilla firefox 22.0 and toolkit 7.0725 [27489]

Hi,

I'm using the latest version of the toolkit (version 7.0725), .net framework 4.0 in combination with the mozilla firefox (version 22.0).

In additon I use the AsyncFileUpload in combination with the ToolkitScriptManager.

Whenever my web page is load a pop up with the error message is shown. The error message is:


A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: http://localhost:57207/ScriptResource.axd?d=Uj7Z4lQIzte_RnIy15eGVAAIOiKFjXb4sJo0HlPrh2MwnZMA9sxKReZ3mjY5Yp9chUs2YuJ7zrjkN8s-R4GZ5Njy2bW75EWzlyd4OB-6LHI0zaLogznc4xp6llL9WdY4G2_zfKtxmCgp_cjaILw8QYt4Yv_RBLHRKHg1swu7tWs1&t=1c4fda5e:194


The same error message I get [ASP.net AJAX Samples AsyncFileUpload Demonstration](http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/AsyncFileUpload/AsyncFileUpload.aspx)

Does anybody know how to fix it, so that I never get the erro message?

Best regards

Tim
