Solution

Add the following registry entries:

Windows

In "Registry Editor" (regedit.exe), add the following under "HKEY_CURRENT_USER\Software\Adobe\Dreamweaver CC\Site OnIdle":

• Type = "String Value" (REG_SZ) | Name = short wait | Value = 6000
• Type = "String Value" (REG_SZ) | Name = medium wait | Value = 45000
• Type = "String Value" (REG_SZ) | Name = long wait | Value = 300000

Mac OS

Edit the file "Adobe Dreamweaver Prefs" at "~/Library/Preferences" and add the following entries for [SITE ONIDLE]

• short wait=6000
• medium wait=45000
• long wait=300000

Note: The above workaround does not stop the message from popping up, but decreases the frequency at which the message appears.
