Do you know about when this issue came up?
It seems that when you make a post, it will send you outside the topic to the parent board there. The reasoning behind the feature, I'm guessing, is because you should read an entire thread before replying (or the parts you care about) and if someone else adds a response before you post you get a mean error.
I never noticed that this is any different than it was before. My best guess so far is that it was an SMF update that changed this.
Happened some when before April 1st. Least that is when I noticed it
I can't speak for anyone else, but I definitely like to read the entire (recent) part of the topic again just to see if my tone and writing doesn't come across in a way I didn't intend, and preview isn't the same, I am old-school and see the post button as something final and often when hitting it, I remember a point I forgot to raise or simply forgot to even include in my post. ;P Preview is mainly for formatting.
It would be pretty wacked if that were a profile setting btw.. gonna check
[_] Return to topics after posting by default
suddenly became unchecked, I assume when you got hax or when updating, it reset "look and layout" settings entirely, because they are seriously not the way I had them set ^^
