UPDATE: Issue-Resolved.

Just wanted to post an update as this may help someone down the road. My issue was that CSSH is using a <<paste>> event to send text to all servers - The paste event is using Selectget, which pulls from either the Primary X buffer or Clipboard, depending on which select=> is defined. So you must either select something or store it in either buffer for it to be sent. I created a few variables with the text needed, then used perls readline to prompt for password once, this is then stored and passed to all the servers on a sleep timer (to ensure the password prompt is hit) Thanks all for taking the time to review this issue..
