Cannot span multiple monitors with 12.1 MRC agent

Forgive me if this has been covered in another thread--I looked through the forum and didn't see anything about this.  I've been running DRS 12.0.5 for a while, and just recently saw that 12.1 had been released over a year ago; I've noticed some quirks in 12.0.5 that I thought might be taken care of in 12.1, so I updated my installation including hotfix 3.  After doing so, I've noticed that if I update the agent on the remote computer to 12.1.0.96, when I hit the "V" for virtual desktop to span multiple monitors, it continues to show just the main monitor instead of both monitors spanned.  If I uninstall the agent and re-install the 12.0.5 agent, it spans correctly, so it almost must be something with the agent itself.  I tried restarting the remote machine after running the update through MRC, and I've also tried installing the latest agent from the MSI installer without successfully fixing the issue.  It's not the end of the world, as I can select the second screen manually, but it's nice to be able to see both monitors simultaneously.  Thank you for any help you can provide!

  • I found the issue.  We connect to our machines with the option "Use MRC's Mirror Driver if available" unchecked because a few machines with full screen applications show corruption when we connect with that option enabled.  In the previous versions of the client (we were on 12.0.6002.5), it would still allow for both screens to show simultaneously; however, in version 12.1.2.584, that functionality does not work unless the mirror driver is enabled.
