However, the fact that lastIndex is actually set to the end position of the last match rather than the position where the next search should start (unlike equivalents in practically all programming languages) causes a problem after zero-length matches, which are easily possible with regexes like /w*/g or /^/mg. Hence, you're forced to manually increment lastIndex in such cases. I've posted about this issue in more detail before (see: An IE lastIndex Bug with Zero-Length Regex Matches), as has Jan Goyvaerts (Watch Out for Zero-Length Matches).

Thank you for the fine software you've made. I own EditPad Pro and RegexBuddy and have gone at least a little way towards learning regex with the latter. Your book would be the perfect way to get in-depth knowledge of the wonders of regular expressions. Thank you and good bye from Norway!
