Welcome to the site, Gary! It's actually not a bad thing when your dough climbs up the hook. It means that it's getting closer to being ready. The trick is to make sure that it's not too sticky when you go to pull it off.
By mixing your dough in your KA, you're reducing your manual mixing/kneading time by a good 50%. The KA instructions say that you can tell the dough is ready when it pulls away from the bowl, forms a "ball" of sorts and climbs the hook. I believe they also say to not run it above speed 4 when you're mixing dough, either.
If the dough is climbing before it's fully kneaded and smooth, stop the mixer, add a little flour (I do a Tbsp at a time) and turn it on again. That should help everything pull together better.
Good luck!
