Go To URL Function in Web client

Hi
"GO TO URL" system function is not working in Web Clients(HTML). It is working in FAT client.

Any idea? I am breaking my head on this? Any idea on this will be a great help to me.

Thanks

It is working.
As I have disabled the button after calling the "GO To URL" function, it throws error in HTML. Now I have removed the disabling the button. It is working fine.

Thanks
