Kelley,
No problem and really no inconvenience. I was just surprised when the f9 function did not work properly. In fact and as info the f4 seemed to engage the "drive hold" feature. I checked the function mapping and that window looked OK. I can't say that too positively because I can't repeat the situation as I re-loaded, from ESU website, the same sound file. After that, the functions seem to work as intended. And besides I just like to tinker and hopefully learn something. Your work, supported by TRW postings, is top notch. And BTW, I just ordered a "4141" LS version. Also, I think the "smart start" is cool. All these types of features , IMHO, is what puts ESU at the top of the sound game.
Thanks for the comment and keep up the good work,
Carl
