I have Win XP Office professional.  My ISP is SBC Yahoo (DSL).  I have Explorer 6 and run Outlook Express 6.  This issue I have is when I send a small attachment jpg or notes file it take forever to load up and most of the times it times out when sending the mail and attachment.  I have no issues getting mail or attachments.  I diabled my notornby deselecting several setting (I found a good site on-line to explain how to disable Norton for incommin and outgoing mail) which eventually stopped my Norton from popping up in the right corner when sending mail.  I also reset my account in Outlook Express but still to no avail to resolve my issue.  I was on-line with SBD and they verified some Outlook Settings and said it was not my ISP but Norton.  That was before I disalbed my norton email scanning.  Norton said it sounds like it is my ISP or Outlook Express Software.  I also went under programs, install and  remove and deleted my Outlook Express (so I thought as when I reinstalled it inder add remove the same settings installed as before along with the same address list)  It does not totally remove the program.  I even read up  and one site stated how one can manually remove some settings for Outlook which will totally remove it.  Unfortunately I followed it and only to find out the system still recogonized my Outlook Express.  I had to hit restore to get it back so I could run it.  My CD I had for my system states it is not the correct one that was originally installed and I could not load it.  I had a pc purchased from work and it came with the disk at hand.  I was able to run my system great until about a week 1 1/2 ago.  I don't remember changing any settings.  Any help would be greatly appreciated.  I was hoping for OE7 comming out thinking that may resolve my settings?  Who knows? 

 

 

Thanks
