I am a non-owner weekend hobbyist! With that said, I do get to use one on a regular basis and am saving to purchase. I upgraded JJ's machine to 3.8.6 and was having problems using the buttons tool. Here are some tips he got from Shopbot tech Ryan during the week while I (hobbyist Ryan) was working. We miss the toolbar, but this works fine too. Soooo far all is good in 3.8.6 land.

1. after you create said buttons, set to production mode for use.
2. to get back to production mode, hit control-shift within a few seconds of opening buttons.

Simple as that to get in and out of production mode. the rest is fairly easily to figure out with some experimentation.

Hobbyist,
