I know. I already tested the last few updates (with a quick deinstallation of the old plug-in version), but it still doesn’t work properly. Some Melda plug-ins have an built-in band filter/eq or a editable graph for custom shaping, which settings are activated/accessed via a double-click or right-mouseclick (like a context menu), but for whatever reason this doesn’t work with the WL 9.5.5 Update (and again, it worked fine in WL 9.5.4 and it works fine in WL 10.0.10 and latest Adobe Audition). But that problem would be a problem for the WaveLab 9 forum.
