I changed to Openworld Broadband about a year ago. At the time I didn't know (read) that they didn't support Outlook XP or in fact IE 6 (only up to 5.5). I having been using both now since start and only had one problem when my OS packed up and needed reloading. Not BT's fault but their operative when I needed to set up Broadband said, 'We don't support Outlook, but if you click this and this...' I was lucky but you can probably sort any problems out yourself, especially with the help of this forum. I'm now battling with BT Yahoo! but that's another story.
