Upgrade?

I just "upgraded" DraftSight.  I cannot find where it says what version, as there is no "about" anywhere that I can find. Here is my question: In previous version, when you open a drawing, it sets the path to that directory, so when you click file open again, the path is the same as the drawing you are already in.  This version goes to a different directory.  I want my old version back, or at least have the ability to use the functions I already had. Why do upgrades always lose something that was working?  It isn't an upgrade if it isn't even as good as it was before. 

It also took me three days to find how to put it into light mode, as it installed in dark mode.
