This really is one of the strangest software bugs I’ve come across!
Dreamweaver crashes and won’t open again. When you try and open Dreamweaver it just closes straight away, with nothing more than a glimpse of the splash screen.
One of the CSS files in the site you were working on has a file size which is a multiple of 8kb (mine was 24kb). You can try anything; rebooting, reinstalling, but Dreamweaver won’t play ball if the file is still there. You need open the CSS file in another text editor and add a few dummy lines of comment text to increase the file size slightly; you should then find Dreamweaver will open again normally.
Thanks to David Powers for this. Please feel free to leave any comments below.
