To all of you guys - we found a way how to add a digital signature to custom configured installers without "going online" with our MSI configurator. So we'll soon implement this feature and any installer, including custom ones, will be signed with our digital signature.
There is currently no idle check in the program. However, you can use another solution. Enable the Ask User permission feature and set Auto-alow on timeout. If the user is there they can access or reject your remote connection request. If there are not there, you'll still be able to connect after a specified time.
Users are able to connect, but when the login screen appears and credentials are keyed in, it reappears with an empty password field. I presume that means the credentials are not accepted thus interrupting the login process.
It means that the access password is either not set or incorrectly typed in.
To set/change the access password, access the Host settings, click Security -> Change password and set/change the access password.
Hope that helps.
P.S. Sorry for the Windows upgrade issue. This is a known bug and it happens because the Host's settings are located in the HKEY_LOCAL_MACHINE/SYSTEM folder which is wiped by Windows during upgrade (hence, the Host settings are reset). Starting the very next update (v. 6.5) the settings will be located in another place in the registry so this problem will be no more.
