I cannot access the audio plugin controls in Movie Studio HD11. I am also having trouble bringing up the plugin chooser. When I left-click on the Event FX icon when it is green, nothing happens. When it is shaded, however, the plugin chooser will pop up. I have removed and reloaded the software several times. Sorry about the twin problems - the most important issue is the fact that every time I add a plugin to the chain, the controls for that plugin simply don't appear. The video doesn't seem to be affected. This was not an issue until about two weeks ago. I would appreciate any and all help you could give me.
