I deleted the Preference folder (or at least emptied it). After that on Start, program begins with “Empty folder” instead of usual default to “Last Folder”. Makes NO DIFFERENCE. As soon as program tries to Save the “new folder” or in fact ANY interaction with Windows file explorer within Wavelab 9, big CRASH. What I wonder is whether PG is using Windows 8.1 or Windows 10 with 64 bit to test this program? A clear statement from him that he has used this O.S. would give me confidence that a fix is near-term.
