Maybe ?
if in "Bulk Rename Utility.ini"
you changed the value of "Favourite Path" to ""
(i'd think you would have to do that manually, or in some automated fashion prior to opening BRU)
But then this too may very well come into play,
File | Open filename.bru does not load Path.
Actually, not clear just how/where things are pulled from & how they intermingle.
You have .bru's & .ini & also some settings are in the Windows Registry?
Oh, & this too,
How To un-Favorite a Favorite?The whole thing is just, rather confusing.
