Great software - easy, simple, no install!!! Just the way software should be. I hope that my little comments help improve hfs.
Included are a few small things that I found:
1) In windows XP, When clicking menu > Help > web site or Menu > Help > Forum a new web browser is not opened. In my case - it caused an upload window to be overrun.
2) If you first input the names of the upload files, and the open the "progress pane" the file names go away and need to be input again
3) It would be nice if a directory could be recursively downloaded or at least multiple file selection. (e.g. a directory with 200 photos could be done at once)
