What looked like a easy task- knock together a CGI in perl to query a db and generate a graph- has turned into a real mire. I have spent several days fighting with doing DHTML on NS4.x on Unix, NS4.7 for Windows, IE5, Mozilla/NS6, Konqueror and IE6. Paraphrasing a line from the text adventure “Zork”: You are in a maze of twisty little standards, all different. In the past I've avoided doing complicated user interfaces, leaving for people who know what they're doing to fight and refight the browser wars. It mostly works on Unix, still working on the IE stuff. At least when I'm done, I'll have a nice little store of knowledge and a library of useful functions.
