It's not at all obvious how to use Visual Web Developer 2008 Express Edition
to debug JavaScript in Internet Explorer.
So I wrote it up at the Cozi Tech Blog.
The JavaScript engines in Firefox 2 (Windows) and IE6
can't handle the new Daylight Savings Time rules in the U.S.
The Date() function returns a value that is off by an hour
if the system time is between the second Sunday of March
and the first Sunday of April.
More at the Cozi Tech Blog.
Update 2008/03/14: Mea culpa.
This is not a widespread problem.
It is caused by the presence of set TZ=PST8PDT
in my C:\AutoExec.bat.
Per KB932590, the existence of the TZ environment variable
will cause the CRT to use the old DST rules.
(I can't remember why I set TZ several years ago.
It's part of the accumulated mess of files that
I bring everywhere with me.)
Over at Cozi, we've started a new technical blog.
I just put my first post up,
describing a nasty problem we had late last year.
Here's the summary:
Internet Explorer 6 does not support transparency in PNG images.
The best-known solution is to use the DirectX AlphaImageLoader CSS filter.
It's less well known that using AlphaImageLoader sometimes leads to a deadlock in IE6.
There are two workarounds.
Either wait until after the image has been downloaded
to apply the filter to the image's style,
or use the little-known transparent PNG8 format instead of the filter.
