But When I disable the Color function of CSS thro'

Tools > Internet Options > Accessibility > [check] Ignore color specified on the webpages

and the warning message disappears.

Hi,

This is a continuation of my previous problem.

To add the headache, another page also giving me the same warning.

when I check both those pages im my workstation's IE, it generates warning in both the pages.
However, When I try the same in my neighbour's workstation, The warning is only on one page.
Both the workstation's IE has been set with default settings only and both IE are of same version.

Is that problem with any other criteria regarding browser?

Please help.
Thanks
