I use Outlook 2007 on a Win 7 computer and 'some' HTML e-newsletters are very slow to open. I click to open only some of the e-newsletters I get daily and sometimes it takes 5 min (or so) for the e-mail to display. I just get a 'system busy' pointer and if I click, I get a gray screen. Sometimes I delete one e-mail and the next one that would auto-open will not display the same way. This does not always happen but nearly every time. Other HTML mail has no problem. I have tried to do a repair install several times but it doesn't help.

How do I make the e-newsletters open like they should all the time?
