To get encryption, you’ll need to download a separate dll and drop it into your putty connection manager directory. At the first start up, it asks you where PuTTY is, so make sure you’ve got it installed. Verson 0.6 is recommended. My first attempts to open PuTTY instances from the Connection Manager left them stuck in the task bar. There’s a timing tweak under Tools >> Options >> PuTTY. Setting it to 200 ms did the trick. Individual hosts also needed a bit of timing adjustment so that the username and password appeared were presented to the proper prompt. Right click on the connection and select configuration to adjust those.
