For the Reply,but it's behaviour is pretty wierd in IE9 . Iam using Buiding Ajax Attachement Table  Example,sometimes it will work and sometimes the button becomes inactive.

And Iam stuck In a place where when Iam uploading the file on the server its showing me the error.

Server Exception 

(1) tmp_name is not available

for " . 09-Examples.pdf

And the same files are being able to upload on my local copy.

Is it because of encoding standards.
