Outlook Express 6.0 with IE 7

Ever since installing IE7, Outlook Express acts a little differently. When I first open OE and go to open a window, regardless of whether it's to create mail, view mail, etc., the window takes about 2 seconds to open. If I don't close out OE and I open another window it pops up almost instantaneously. When uninstalled IE7 (didn't really care for it) this does not occur. I am just curious as to what's going on. Any ideas? Thanks in advance.

Why bother with OE? It's crappy. Use thunderbird.

You're right! There's no comparison, Thunderbird is worlds better!
