ABAP Autocomplete does not work

Hi Experts,

can anyone explain why the abap autocomplete does not work in SAP Logon 730?

The Problem:

Code completion in ABAP does not work, as a list of proposed Code is shown but it cannot be selected via pressing ENTER.

(The problem occurs accordingly to previous SCN question http://scn.sap.com/thread/3589332 which is still not solved.

We already changed the value )

Any hint would be appreciated.

Thanks and best regards

Vanessa
