Removing the "sapUrMapi_ie6.js" Javascript files..

Hi,

When we logged into the Portal, the below Javascript files are getting downloaded. The size of each file is above 200-300 KB.

1) popup_ie6.js

2) sapUrMapi_ie6.js

3) controls_ie5.js

4) pagesupport.js

etc....

Can anybody give some idea, How to remove these JS Files from downloading..

Thanks in Advance.

Thanks & Regards||
