I had been having some problems dealing with Leopard's Screen Sharing feature -- I wasn't able to remotely connect, no matter which ports I opened or prefs I turned on, using a machine from my job running 10.4.I was attempting to connect with Chicken of the VNC (CotVNC), and according to a few articles across the web, it should have worked flawlessly. It certainly did on my network at home, so I wasn't sure what I was doing wrong. I even DMZ'd my machine at home -- still, nada.Then I was playing around with the Profiles options in CotVNC, and there's a setting where you can change the resolution of the window on the client's end. The choices are 256 colors, Thousands, Millions, and Let Server Decide. I always had it set to 256 at work, because I was more interested in speed than how pretty my desktop looked from afar....
