I am running Windows XP Pro SP2 with Outlook Express 6. My Internet Explorer lists as version 6.0.2900.2180.xpsp_sp2_rtm.040803-2158 (what a mouthfull!). My problem started about two months after installing SP2, so I don't think it is an issue with that. When I try to open a weblink sent in an e-mail, such as to a reply to a post on this forum, OE locks up. I have to do CTL-ALT-DELETE and shut OE down with task manager. I have not changed any setting, nor does AVG report any virii. Everything else in OE works fine, but it is getting a little annoying having to copy and paste weblinks into my browser window from e-mails.
