I hope this will avoid headaches to system administrators: - MSIE 5, when installed, changes silently the setting for the cookies to "Accept always" no matter how did you have it in IE4 before. This is because M$ changed cookies configuration from the "Advanced" to the "Security" tab. - MSIE 5 cannot be used with cookies set to "Prompt before accepting" when visiting sites that send many cookies: after choosing NO (reject) to each cookie more than three or four times, MSIE will crash with a memory error. I was able to repeat the crash in some NT systems: a generic computer, a Dell computer, etc. Look for a cookie intensive site, like www.celebsite.com and see for yourself. I never saw this to happen on MSIE 4 SP1. - MSIE 5 includes a new "Allow per session cookies" setting, that's enabled by default. I think session cookies are less dangerous than persistent cookies. - By default, AutoComplete will offer to save passwords used on sites you visit. Be careful, because while you are typing to fill in a form, if you continue typing, you may press the "Y" as part of your text just in the moment the popup window ask you to save the pw and you won't notice what happened. - MSIE 5 created a service called "COM+ Event System" no matter I downloaded first all files and later I installed custom. What is this service intended for? I remember that after installing RDS (part of M$'UDA), I discovered some RDS objects where opened to anyone that knew how to connect to them. I hope this time, the new service won't open a new security breach. Note that all computers had NT 4 SP4 installed and it's the US version.

Also, if you have an old cookie from some site on your disk, and you revisit that same site with the cookie setting adjusted to prompt for acceptance, no prompt is given, and the cookie is automatically written to disk anyway. Ouch. this was observed on NT Workstation 4.0 with SP4, where I had installed IE5 as an upgrade to IE 4.01.xxxx for the record, i've never seen my installation of IE5 crash due to not accepting cookies (or any other reason for that matter.) i tried this at www.enanet.org, where that sites sends a vertiable truckload of cookies at you. maybe they should rename the site after the keebler elves ;-] mark > I hope this will avoid headaches to system administrators: > - MSIE 5, when installed, changes silently the setting for the cookies to > "Accept always" no matter how did you have it in IE4 before.
