Ok, this is a wierd one. I was trying to discover why Adobe Dreamweaver CS3 was crashing and I couldn’t figure it out. After some googling, I found the Dreamweaver CS3 Read Me (pdf) file which states on page four:

Known Issue: Crash in Windows when CSS file size is exactly 8192 bytes, 16383 bytes, or specific larger sizes Dreamweaver crashes in Windows if you make an edit to a CSS file that changes the size of the file to exactly 8191 bytes or an increment of 8191 bytes. In addition, Dreamweaver won’t restart unless you change the size of the CSS file. To change the file size, open the CSS file in another text editor and insert a character or two, including whitespace characters such as spaces and tabs.

Now, isn’t that the oddest thing you’ve ever heard? This is exactly what happened to me and I had to open my stylesheet in WordPad and add some comment lines to bring up the file size. Too weird.
