Page not found when using context help on Sandbox

CIS 4.1.x.920, Windows 7 x64. I get contextual help properly on everything in Comodo whenever I click “what do these settings do?”. However, The help displays a “this page could not be displayed” error when I try it on any of the Sandbox features. The help contents are there, manually looking them up makes them readable. But the contextual help can’t bring them up.

Hmm confirmed, well sort of, I get CFP locking up when I click from General Settings tab!

Best wishes
