The latest NTB "fix" for Chrome v32 "mostly works" on my NIS v21 test system, though the jumpy floating rendering of it is quite annoying. The problem happens when the webpage display window for a website (i.e., Yahoo) is scrolled... The NTB will randomly jump to various locations down the page as the page is scrolled then it will suddenly snap back to its normal top-of-page location where it then causes the entire webpage to be adjusted downward to create space to accommodate its top-of-page location...
The test system is configured with the Windows 8.1 Pro OS using only the drivers supplied by Microsoft with the Win 8.1 Pro OS and subsequently updated only via Microsoft Windows Updater.
Kind regards,
John
