I am using a VOIP8551B/26 Skype phone. When opening Contacts through the "S"-button, I can only press the down-arrow 5 times, and then the navigation gets locked (can no longer move up or down in the contacts list). The only way to get out of this menu is to press the back-button. Since navigation gets locked, I assume this to be a telephone and not a Skype issue.

Another thing that currently doesn't work is the feature when pressing the first button of a name, the list with name starting with that letter does not pop up. Looks like there is something terribly wrong with the contact list.

I have tried to reset the phone, turn it on and off and remove the batteries for a while - no progress. Any idea how to solve this?
