I think this is a recent bug in the betas but I'm not certain when the functionality was lost.

If I right click on the recent sessions list on the DF task bar icon for putty, it does nothing. It is currently pinned. Unpinning does not resolve the issue. The tasks section also does not work.

Also, the name is incorrect. It is supposed to be PuTTY but it is SSH, Telnet and Rlogin client.

Just some small bugs I've noticed. Not a show stopper for me.
