Ed-- I said what I said because I have had issues with other VIs wonking out in different ways in DP and not in other DAWs. Recently, I had to use Logic to authorize an AU when DP would reject it. Once it passed Logic's AU Exam it worked fine in DP. Also-- one of DP's own VI's had to be manually uninstalled *after* the latest update was done and then reinstalled before it could work. I and others traced this issue to specific DP '.bundle' and '.component' files that were the culprits. It has happened more than once.
At the very least, a fix will have to be the result of a collaborative effort between host and plugin developers.
