UAC - Cannot see dialog box
I have TV 12.0.83369 installed on a Win 10 PC I support. TV is installed to start when Windows starts (runs as a service), and does indeed start and run just fine. The problem I am having is that the remote PC's user id is a non-admin id (Standard user), and when I attempt to update software on the box the UAC kicks in (as desired) and pops up the admin prompt requesting credentials to proceed with the installation. However, I can only see a black box where this dialog box is and I cannot enter the admin password or see the dialog box buttons. I never had this problem in the past with this machine, so I am not sure if it is a problem with a Win update or a TV update. I do not have this problem if I log into the admin account and do updates from there (this is more troublesome that just doing it in the user id). Any ideas or settings I could check in TV to respond to the UAC prompt in the user id?
