[Bug]:"Show notifications on state change" Settings option : Activating tunnel causes unhandled exception #48

Closed JimBlankenship closed 5 months ago

JimBlankenship commented 5 months ago

When the "Show notifications on state change" settings option is selected, activating or deactivating a tunnel causes the following error dialog to pop up. No other settings options were selected.

The logged in user is not the administrator and not in the administrator group. Unchecking that settings option causes that exception to not occur during activating or deactivating a tunnel. However WireSockUI was UAC'd to run as Administrator when it was launched.

System is Windows 10 22H2 19045.3930 WireSock VPN client: v1.2.37.1 WireSockUI: v0.2.1-AnyCPU

WireSock VPN client was upgraded from v1.2.30.1 WireSockUI was upgraded from v0.1.7-AnyCPU After installing these versions, the system was rebooted.

This problem does not happen when the UAC dialog is dismissed at launch (WinSockUI is running as a regular user).

Unhandled exception dialog:

** JIT Debugging ** To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.

For example:

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

This problem does not occur when WinSockUI is launched as a regular user. This happens when the UAC dialog is dismissed. Solution is to not run WinSockUI as Administrator. Alternatively, the setting, "Disable Auto-Admin Elevation" can be selected to prevent the UAC attempt.
