Do you use firefox?
If you do look under Tools addons and look for gamevance textlinks
Must have been auto installed on my last firefox update.
Drove me batty it did..
first you need to disable the durn thing
then uninstall the durn thing well that didn't work for me even tho I uninstalled the darn thing 3x..so.
I hadta go to
Control panel
Add remove programs
and get rid of it there.
That should hopefully get rid of those annoying green lines everywhere
