Dave here again. Just registered properly. I have just gone back to trying HFS again after not bothering for some time. Even resorted to shutting down virtually everything else running (including security programs), using a program called "EndItAll" and HFS still would not start, even with a fresh download. Just a little hour glass activity and then nothing. This is on both my machines, but I can't think of any common factor, especially as it was going perfectly OK previously. As it's only a stand-alone .exe, what can go wrong? Maddening. It doesn't make sense to me. Any ideas? Does it depend on a service that I might have shut down or any other factors involved? A Windows update? Clutching at straws here. Desperate to get it going again, as I find it so useful when on Messenger to send files, rather than actually send them through Messenger, as it is a tad slow.
