Please try the following:
Save all work and close any open applications.
Uninstall Viscosity (Keep your settings and connections).
Navigate to C:\Program Files and force delete the Viscosity folder if it still exists.
Empty your Recycle Bin
Restart your PC
Reinstall Viscosity, using a copy downloaded from our website (https://www.sparklabs.com/viscosity/download/
) rather than any you have stored.
Connect Viscosity, hanging your task bar
Open Task manager and go to Details
Is Viscosity using anything above 1% CPU or 100,000KB of Memory? Watch it for a few seconds, is the Memory usage climbing rapidly?
Kill Viscosity - Does the taskbar become responsive?
Kill openvpn.exe - Does the taskbar become responsive?
Wait at least 10 seconds then Kill ViscosityService.exe - Does the taskbar become responsive?
Are there any other tasks using a high or a constantly increasing amount of Memory or CPU?
Are there any tasks listed with a Status of Not Responding?
Kill dwm.exe, your desktop should reload. Is your taskbar still unresponsive?
Ideally, we'd like you to then start killing other processes and testing if the taskbar becomes responsive.
