kmenu: focus always in search field after first invocation

Hello, when I start kmenu the focus is not in the search field as I remember it having been since long and as it is in a newly created user account. That is the behavior I'd like to have to be able to directly utilize the incremental search feature to jump to a certain menu entry by just typing some characters. Problem: in my current long time user account every second and following time I invoke kmenu the focus is _in_ the search field so I have to first push arrow up or down to get the cursor out of it to directly jump to menu entries by just typing characters. I couldn't find any configuration for that. Any ideas what I could do or try? Regards, Stefan
