I was testing the nightly build to see if it resolved my office issue on snow leapord and it did not so I figured I would give IE7 a spin
Just a heads up It does seem to work but again https fails on a lot of sites for instance if you specify https and a port
https://127.0.0.1:10000 (webmin port)
it flashes the screen for a millisecond and then you get the dreaded
Internet explorer cannot display the page error
If you need more info let me know
But I assume you have linux boxes webmin might be an excellent way of testing https and port specification all at once
