I had quite an old version on my previous mac, so it's new for me! Consider this (using DualBrowse):
If I have 2 files to update on a site, one in /www/images/ and one in /www/, I cmd-down to /www/images/ and transfer the first file, then cmd-up back to /www/ and in my old version I could then transfer the second file without having to do anything in the remote window.
Now, after I cmd-up back to /www/ I have to first go to the remote window and move the highlight *off* the sub folder, THEN go back to the local window and transfer the file
an extra step that I find moderately annoying! (And before you suggest I could transfer the /www/ file before the /www/images/ file, well yes i could, but it just doesn't always happen that way!)
