So this is a one-man project that offers it for free and someone has the balls to complain because it doesn't support (for valid reasons or whatever) his particular (broken) browser? If it's so important to "business types" to support IE here's an idea: make them pay a fee so it covers the extra development costs (this is not outrageous in general; there are open source projects that cost money for the Windows version). This is not a government site or an Amazon that has to please everybody. I bet none of the people complaining have ever suffered trying to code around the IE compatibility problems.
