I can install and run ZD 7.1.4 on Mac OS X client one time and it opens fine. If I reboot the workstation and open ZD I get a blank white window with a spinning red circling "clock face" and eventually the error message that says:
Warning: Unresponsive script
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
I have searched everywhere and cannot seem to find a resolution.
