Suddenly cannot spy any browser elements beyond window

Greetings,

Up until today, I have been able to use TestComplete to test our (web) application. Suddenly, however, I am not able to spy any objects contained on pages, only the container "Window". This happens in Firefox 48, Edge, IE & Chrome. I also tested other sites like google.com and it is still only spying the window. Up until lunch time today all were working fine. I have tried closing testcomplete as well as restarting my computer, but the issue still persists.

Any suggestions on how I can start spying my page objects again? If I go to the NameMapping editor and select a control, then tell it to highlight on screen the control is highlighted, I just cannot select it with the Object Spy tool.
