Behavior observed in Vista:

• "Pro Tools application has stopped working. A problem caused the program to stop working correctly, Windows will close the program and notify you if a solution is available."

Behaviors observed in XP:

• Pro Tools will begin to launch, load plug-ins and stop loading (get stuck) at structure.dpm or another plug-in file name.
• After attempting to launch the Pro Tools program, an hour glass appears for a moment then disappears. (Task Manager > Processes may show Protools.exe as a running process)
