Single Click Stops Accepting Input

Post by networkn »

Hi There!

We have Single Click compiled with the latest online version and are using 1.1.8.6 on the listener end. We have noticed that quite frequently, when we are working remotely, our ability to use keyboard and mouse remotely seems to stop. We can SEE what is happening at the other end, but not click buttons or type any longer.
Disconnecting and reconnecting fixes the problem but then it happens again.

Any ideas what could be causing this?

SC run as application.
"system windows" are protected by UAC and only allow input by other UAC started apps ( or services).
If a UAC started app is on foreground, it block all input and you are in view only mode.
As soon as this window is minimized or close you get back full input access.

If you start SC also elevated "runas admin" you are at the same level and keyboard/mouse keep functioning.

Is there no other way ?
Is there some way to get an indication that this has occurred?

Temp disbale UAC for admin ( helpdesk.txt option)
But then SC ask permission once during startup and need to be accepted by the user.
After that no more popups or keyboard locks.

There is no indication in the SC version.
The only thing is that when you open a special window, UAC popup.
