In testing a site I am working on today I was going to fix some of the issues that IEs had in rendering the site using conditional comments. Come to find out that in using a multiple IE set up, all versions are "detected as the latest(usually 6)" some source said. This would make sense as when I was trying to experiment with conditional comments I could not get them to work (newb to conditional comments).

my question is...
How do you guys/ gals develop on one machine and test across browsers when using conditional comments.

I did end up solving most all issues with a single style sheet mostly using !important and then redeclaring the rule right after that seems to fix them for ie 6 and 5 since they don't listen to !important. Let me know if this is a bad idea. Also let me know if I need to be more specific on something or if this made no sense at all.
