Every time I travel and change Time Zones, DP requires my keycode when launching
Due to the architecture of OSX and our authorization method, DP (versions 4 and higher) is authorized for the Time Zone you installed under. We are looking into this matter to be addressed in a future update/upgrade. If you are traveling and using DP, we would recommend simply changing your time zone back to the time zone at which you installed under when running DP and DP will not require a re-authorization.
