Issue

When you try to open a document in Dreamweaver CS5 or CS5.5, it takes anywhere from 30 seconds to several minutes for Dreamweaver to open it. Dreamweaver stops responding until the document opens.

Solution

Disable Dreamweaver's Resolve To IP Address feature using the instructions for your operating system.
===========

Mac OS

Quit Dreamweaver.
In the Finder, navigate to the following location:



/Users/Your User Name/Library/Preferences


Open the Adobe Dreamweaver CS5 Prefs file (CS5) or the Adobe Dreamweaver CS5.5 Prefs file (CS5.5) in TextEdit.
Locate the [REMOTE DOWNLOAD] section in the file. It looks similar to the following:



[REMOTE DOWNLOAD]

remotedownloadcachesize=50

remotedownloadallow=TRUE


At the bottom of this section, add a line that says: resolveremoteurltoipaddress=FALSE

The [REMOTE DOWNLOAD] section now looks like the following:



[REMOTE DOWNLOAD]

remotedownloadcachesize=50

remotedownloadallow=TRUE

resolveremoteurltoipaddress=FALSE


Save the file, and then quit TextEdit.
