Hi,

   we're using the Ajax Uploader as silverlight conponent since many year and it works great. 

   Recently, we came across the unavailability of the component but, only for a little bunch of users : instead of poping the Select File Dialog , it looks like the InsertButton just do nothing when clicked. This was observed on IE9 23bit and Firefox according to the users.

   In our end we tried to reproduce it without success. Well, the only way we got the same behaviour was by uninstalling the Microsoft Silverlight component (the component have been verified on the user end and, it is well installed) ! 

   For exemple, this behaviour have been found yesterday (September 20th) during all day. Then suddenly, today, the problem have gone, and the component correctly popped the Select File Dialog for every users who were have the problem! There have been no updates on both side between yesterday and today.

    Did you ever got any problem reports like this ?

    I've found some interesting description of a similar behaviour regarding Microsoft Siverlight automatic update feature : looks like when automatic update feature is on, it may block a Silverlight component form running. It is than recommanded to turn it off.

   Do you know if the Ajax Uploader can be affected by this problem, and could block its execution ?

   Thanks in advance !
