Jumping of cursor to the top of the screen once enter is hit

Hi ABAPers,

I would like to ask for your help regarding this issue.

When user hits enter button in a Field, in an ALV cell, or any blank space in the screen, it will reload and the cursor and scroll bar jumps to the top of the screen even if the current cursor is in the middle or last part of the screen.

This is happening in a webgui particulary SAP Netweaver running in IE11 browser. But not in R3 environment.

Let me know your thoughts on this. Thank you very much!
