While writing my latest book, I discovered that Dreamweaver crashed
every time that I changed a measurement in a particular stylesheet from
5px to 0. Not only that, it consistently crashed whenever I tried to
restart Dreamweaver, and the only way to solve the problem was to delete
the style sheet. Since the style sheet was installed by the Spry Tabbed
Panels Widget, I wondered if there was a bug with the widget, so I
contacted Adobe.

The answer revealed one of the most bizarre bugs ever. Dreamweaver CS3
crashes if you create a file that is exactly 8,192 bytes (or a multiple
thereof) in length. Try moving your sites (or the contents of the site
folders) temporarily to a different location, and see if Dreamweaver
launches. If it does, it's then a question of locating the file that's
causing the crash. I solved my problem by using 0px instead of 0. That
added 2 bytes to the file size, thereby avoiding the bug.

I understand that Adobe has identified the cause of the bug, and that it
will be eliminated in the next release (I'm hoping that means an
updater, but I don't have any information about that).

As I say, it's a long shot, but it's worth trying.
