i recently updated viewer & host software to vers 7.0 as well as received and updated my new license key on my computers; some win 8.1 and some win 10. the server software vers 3.0 is installed on a win 8.1 64-bit laptop. i noticed connection issues that i never experienced with server vers 2.7.
a connection would be made but had no control over the host computer despite full control mode being active. this would happen after the host computer went to screen saver mode. and the connection would not deactivate the screen saver. this happens to both win 8.1 and win 10 computers.
i have since reverted back to using server vers 2.7, still using viewer vers 7.0 & host vers 7.0 and have not had the issue.
