try making a simple script like this
Code:
#! /bin/bash
cd ~/.wine/fake_windows/Programme/Traktor\ DJ\ Studio\ 2/
exec wine TraktorDJStudio2.exe
and save it as traktor or whatever you want and do
then move it to /usr/bin (note that you may have to do it as root)
Code:
su <your root password>
mv traktor /usr/bin
after that add an entry to your kde menu and as the command put "traktor" and try to run it that way
PS. I'm just starting with bash scripts so it may not work
