why in a assembly I can not edit a part
Right click on the part itself or part in tree and select the edit part icon. You can also select open part and edit it in it's own file.
That wasn't very helpful.
Your suggestion has been a known for years. The problem is that "in-context editing" crashes solidworks consistently. THAT is a problem. Solidworks was designed specifically for in-context editing and the inability to do so is making the program pretty much worthless.
Derek gave you the best possible answer with the information given in the first post. I don't remember anyone else here reporting problems with crashing when editing Parts. Have you gotten your VAR involved? Is this just one assembly, or more?
The first post wasn't specific on why he couldn't edit a part in an assembly. This just started with 2015 and happens in more than one assembly. I'll have to get my VAR involved.
I don't see anything in the original post a mention of a crash. Also what may seem like a simple well known answer to you may in fact not be to others. The purpose of a forum is to help all levels of experience. If you are having problems with crashes I suggest you contact your VAR or start a discussion on your specific issue.
