Version 17.5.2 is available so I hoped to update from 17.4.1.
I tried the golden label at top with announcement. "Download" button did nothing except make the golden label disappear. No download occurred, even after 10 minutes.
Later, I clicked on browser's main button and clicked "About Comodo Dragon" and a download immediately started. After 5 or 6 minutes this download finished. Within this same dialog was offered a choice to Relaunch and Install, so I chose this. The browser simply closed and NOTHING else happened. NOTHING!
Same problem here with three different operating systems:- XP, Vista & 7 ?
Had to do a manual download and update

Great browser tho

Keep up the good work team
