Got this neat trick through Don McArthur.com...
..via Daring Fireball
...Here's the line I added to the end of my /etc/hosts file
After saving the hosts file, Tynt's clipboard-altering nonsense is disabled on all Tynt-using websites I've encountered, no matter which browser I use...
So here's a screen print of my Windows XP - C:\WINDOWS\SYSTEM32\DRIVERS\ETC\HOSTS
To find easily in windows: click 'start' ---> click 'run' ---> paste above in the window ---> click 'OK'.
I've added the line at the bottom: 127.0.0.1 tcr.tynt.com
(click to see larger image)
Whoops! I'm not good at following simple instructions. The way this works is to add the code (127.0.0.1 tcr.tynt.com), to the BOTTOM of the list!
Then it works.
