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 Saving 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).


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


  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.
