Unfortunately, we couldn't reproduce the issue. Could you please let me know if your remote Host is updated to the latest 188.8.131.52 version as well? In addition, try enabling the Use legacy capture mode feature in the Host Settings -> Other tab and see if this helps to resolve the issue. Please make sure to restart Host after enabling the feature in order for the changes to be applied.
Marco, as David correctly mentioned - the remote monitor remains blank (i.e. it's blacked out), so the remote user does not see your actions on the remote screen. In the newer versions you can also set up a text that is displayed on the remote screen when it's blanked - you can set it up by selecting the Set text for blank screen... button: As for the issue - we have the new version 184.108.40.206 scheduled for a release today (Wednesday), so in this case I can suggest that you wait until the release is available on our website, then update both Host and Viewer and see if the issue still persists.
Please let us know if the issue still persists after the update.
This is to inform you that we've just released an updated version 220.127.116.11 with a few fixes for bugs/issues found in the previous release.
Could you please try updating your Remote Utilities installation and see if this helps to resolve the issue? The latest 18.104.22.168 version of Remote Utilities is available for download on this page. You can also update your installation via the Self-Update method. Please make sure to update both Viewer and Host/Agent to the same version in order to avoid the version mismatch.
