When I log in through IE 6.0.2800.1106 (W2K) or IE 6.0.2800.1106.xpsp2.030422-1633, it caches mailbox pages. If I don't close the browser on a public workstation, other people can see messages that I've read. I don't see this problem with Netscape 7.1. IMP 3.2.2, Horde 2.2.4. Is this a known issue? Thanks, John Dalbec
