Hi staffsmatt
HFS would be a really useful tool for us but our users are not really up to fiddling with setups - it needs to "just work".
Even if you seem to experience something else: hfs just works. Users (clients that connect to the server) do not need to setup anything. The only setup required is on the pc where the server is installed: users, options un definition of the filesystem of the server.
HFS needs no java, no flash, and for very simple templates it even does not need any javascript. Some templates that you might use, however, use at least javascript and some may use flash.
I'am not able to follow all the tests you have done
I can't upload the file to gmail using IE either (but can on the original HFS server) and disabling the flash plug-in in IE allows gmail to work but not HFS...
... you should try to relax and do your tests in a more sistematic manner:
1. If you want to install your server on another machine, DON'T copy the filesystem from one machine to another: create a new simple filesystem and one or two users.
2. Use the original template, not one with flashuploader.
3. Try using a actual beta version 2.3, build 248 (it works so fine as the stable version 2.2f)
4. Y suppose you are using windows XP - am I right with this?
5. Are you in a corporate lan? and have you admin rights on all machines with upload problems?
IE7 and IE8 are the most spreaded browsers beside firefox, and nobody reported such a problem like yours, so i suggest that the problem is in your systems (dammaged installs, access right problems, some security software..) Ask somebody outside of your network to access your server and to upload files for testing purpose.
Good luck!
