Above class SAPBtnStd is used in anchor tag <a>, background-image: url(button_Upload.gif); is used for the button.
On clicking Upload button (which is image under anchor tag) the progress bar is not coming on status bar which should come.
It comes if I remove background-image: url(button_Upload.gif); from my css but I have to use image and I can make the changes in CSS only

Can you please tell what is the reason of progress bar not coming in status bar and what is the solution.
