Office 2003, I know, it's ooooold.

I recently installed this on Windows 10, imported the NK2 file from the old computer and all is working fine.
Unfortunatly the cached addresses don't work as expected.
When I write a couple of letters in the to field all the suggestions comes right up but as soon as I click on one of them or use the arrow keys on the keyboard and select with enter all I get is a new row.

In short, I can't select the cached addresses.
