If you encounter a problem with mouse or keyboard input not responding after successfully connecting to your Sandbox instance please do the following:
Step 1: Close any open connection in NoMachine to your Sandbox
Step 2: Click "Connect" to the Sandbox instance you want to connect to
Step 3: During the launch of your Sandbox instance, you will be stepped through several options and eventually, you will be prompted with a "Display Resolution" selection screen.
- Un-check the option Change the Server resolution to match the client when I connect and the instance will allow proper input function.
