I recently ran into the need to remove and re-install BRU. Kept getting a unique error. Problem resolved with a clean install.
But perhaps my memory is failing me, but I was pretty sure that when I went to a folder, highlighted the files in it, and clicked Bulk Rename Here from my context menu, those same files were selected automatically (still highlighted).
Now I have to go to the menu and "Select All."
Did I just think they were selected before in the application or is there some setting where when from the context menu, selected files are still selected in the applications window?
