Yes I did. In fact that was the first thing I tried. It does recognize the Event plugin as it's own menu system. I can disable widgets for that plugin but only on the individual event page but not on the calendar page.
I'm playing around with every possible configuration and nothing working on the main calendar page.
And it's an all or non sort of a deal. On the Events menu within dynamic widget if I click on "Show Widget on Events" as yes, then click the individual event that says "Except for: [EVENT NAME]" it doesn't work. I have to click on "No" to exclude the widget. All or none.
I will see about creating a screencast to show you what I mean.
