I have only edited one Program. Didn't notice any problems. The display has never blinked.
The Style Menu display exists, but really doesn't bother me. I just have to remember that the style menu goes to the last family I used BEFORE calling a registration up.
I would prefer to work the other way, but I'm not sure it's a bug. It may be intentional that it works that way.
My "problems" are more of nature that the physical aspects don't fit me very well, rather than software or operational issues.
