At this point this is an intentional bug; the -path options are not really implemented yet, and -path, -file and -string are all treated internaly like they were -file. In future versions we will change that. (But not 4.4.1 yet.) I was kind of disgusted that a different browsing function is needed for selecting files and folders. (For -string options there should of course be no browser at all, but that will put the burdon on Polyglot to decide how to pass the UCI string options to WB.) The browsing only serves to get the filename, though. It won't automatically do anything with the file you select. So an acceptble work-around is to just select any file in the folder you wanted to select, and then delete the filename part of that in the text edit.
Sorry about that, but the Engine Settings menu really needs a lot of work, still (like real spin controls, better formatting to not cut short option names, etc.).
