mel1950: how do you clear the cache.
This hasnt been answered as yet.
Apologies, here is another way:
Settings/ History/ Clear Browsing Data (will show similar 'obliterate all items' panel as in Chrome)
Or as long as you have Comodo in Focus, (click on the title bar or in a blank area within)
Press 'CTRL/ SHIFT & DEL' will take you directly to that panel.
This also clears all Flash Cache.
