Troubleshooting
With Desktop Transporter being a very network oriented application, there are many things that can go wrong. A number of common problems, and their solution, are presented here.

Desktop Transporter appears to hang when connecting
Desktop Transporter may appear to hang (as indicated by the spinning rainbow of death) in cases where the remote host is not responding. This is typically caused by the remote host running firewall software, and is most easily solved by opening port 7001. If your Mac is running the default firewall software, follow these steps to open up port 7001:
  1. Open System Preferences
  2. Select Sharing and click the Firewall tab
  3. If the firewall isn’t running, the firewall is not the cause of your problems. Read on below for other possible causes.
  4. To open port 7001, click New and select Other in the menu that appears.
  5. Enter 7001 in the field for port number, and a description (such as "Desktop Transporter" or similar)
  6. Click OK, and make sure that the checkbox for Desktop Transporter is checked in the list of open ports
Finally, note that you need to open port 7001 on the computer to which you are trying to connect. The firewall status of the client Macintosh is of no importance, unless that Mac is also sharing its display.

NAT Problems
Another problem is caused by NAT (Network Address Translation), in cases where you attempt to connect manually to a remote Macintosh. These problems are in general difficult to fix without detailed knowledge of the network infrastructure, and won't be dealt with here.

Finally, if you don’t see shared displays in the list of shared displays (or not the ones you are interested in), there are a number of things you can do:

Problems interacting with the remote display
In some cases, you may experience problems interacting with the remote display, either in fullscreen mode or in windowed mode. First, make sure that the Only observe checkbox is unchecked -- otherwise you will not be able to interact with the remote display at all. Also, ensure that the computer sharing the display has the "Allow others to interact" checkbox in the Sharing tab checked.

A common reason for problems or inconsistencies when interacting with the remote display is that the state of the modifier keys (command, shift, option and control) has become inconsistent. This means that the remote computer thinks that, for instance, the command key is pressed, whereas in reality it isn't. To fix this, simply press and release, in turn, the modifier keys on your keyboard. This should return the remote state to normal, allowing you to interact with the remote display as usual.

Other problems
For other problems, you can contact Yellow Lemon Software, and I will do my best to help you solve them. Registered users will naturally be given more attention than unregistered users, but I will do my best to reply to all requests for help.
