Need some help from those in the know. When I select a plugin (such as Brightness and Contrast" and drag it to my video in the timeline, I can't see to figure out "why" the dialog box doesn't pop up any longer. It did at one point in time. So in other words, I am not able to further "edit" any settings on the plugin I select. How to I enable the dialog box?
