Like I always say…check your DOCTYPE. or remove it completely. Learn your DOCTYPES it is very important. Also Import and link your css (it is essential that you do both depending on what you are using in your css). It is not always so much the browser as it is inexperienced developers. I am usually successful getting my sites to work on a variety of Browser/OS combos. Dont forget about the OS you are viewing on also. That makes a big diff. IE6 on Win2k will behave differently than IE6 on XP…Like wise for the MAC stuff.
I recommend learning your audience and keep up with web standards and trends. IE is still hoverign around 95% of the free world. So dont kill yourself too much shooting for a .09% browser. What I strive for is a graceful degradation.
