Setting for time length accessed link color is changed

Archived from groups: microsoft.public.windowsxp.customize (More info?)

On ebay when I access a listing, the color changes on the link but
often returns to its blue, unaccessed state within a few hours, with
the result being that I don't know if I've looked at the listing or
not. Could you tell me where the time period is set? It's possible
that I have some non-related software that is tidying away these
accessed links..

Thank you.
