A lot of the time now, but not every time, when you paste text in the middle of a line of code it'll move the insertion point to the end of the line which is really annoying cause I'll both lose my place, and start typing where the text isn't meant to go.
It doesn't seem to happen here. You can disable Tools - IDE Options - Auto Format When Pasting. It will most probably prevent it.
You can still format the code by clicking on Alt + F.
