Object doesn’t support this property or method

Debugging Javascript is infuriating. I have a script working OK in Firefox, but it's broken in IE. The error message provided by IE is: "Object doesn't support this property or method" Which object? Which method? The specified line number is a complex little DHTML nugget employing about 7 objects and methods. The lovely thing is, IE must obviously know what object and what method, but they've decided it's better to let me figure it out by trial-and-error. Imagine the thousands of days of human effort that could have been saved if platform developers took an extra few minutes to create more precise and descriptive error messages. I personally could probably bank a 3-week-long vacation on the number of times I've refreshed to see "Object doesn't support this property or method". Microsoft, get your act together. and by the way, Vista DOES suck. peace out
