Web UI issues with RDP sessions


We have Safeguard for Privileged Passwords, version 2.11 installed and we have two issues with the Web UI:

-First issue:

When a user requests a session and click on the play button to start the session it shows this message: 

"Session launched. If your session didn't appear to launch, make sure you have an application registered with your browser to handle the session type."

It never launches the session, we tried different browsers but same results. Any idea how to resolve this issue?

-Second issue:

If a user downloads the RDP client to start the session, it asks for a password, user would think this is a session request not a password release, user can type any password to run the session, this is kind of confusing. 

This is different experience using the desktop client, its more robust and straight forward. I hope I get some answers or fixes for these two issues with the web UI.
