Last week at the office Dreamweaver CS3 kept crashing on me when I was working on PHP files. In the end it crashed almost instantly after I opened a file. Very annoying indeed! Instead of re-installing etc. I did some googleing and found the following issue explained several places including on Adobe’s support pages.

Issue

Adobe Dreamweaver CS3 crashes when working with certain PHP or ASP files in Code view or Design view after the clock goes back one hour, when Daylight Savings Time ends. The crashes only occur when selecting certain lines in Code view, or selecting certain objects in Design view. The crashes only occur in files that have PHP or ASP code, intermingled with HTML code. The crashes do not occur in Dreamweaver 8 or earlier (Ref. 229536).

Reason

The Dreamweaver CS3 WinFileCache-AD76BB20.dat file has been corrupted by the time change.

Solution

1. If Dreamweaver is open, quit the application.
2. Delete the WinFileCache-AD76BB20.dat file from the Dreamweaver user configuration folder. Note that on Windows, the Application Data and AppData folders are hidden by default, so verify that your Windows Explorer folder options are set to View Hidden Folders. The location of this file is as follows:
   • Dreamweaver CS3 on Windows Vista:
     C:\Users\[username]\AppData\Roaming\Adobe\Dreamweaver 9\Configuration
   • Dreamweaver CS3 on Windows XP:
     C:\Documents and Settings\[username]\Application Data\Adobe\Dreamweaver 9\Configuration
3. Restart Dreamweaver.
