Ok guys.. i am getting really upset

Tom,

I wonder if #2 on your list is the related to the issue I’m seeing? I’ve created an entire plugin solution to demonstrate the issue I’m having with not being able to interact with the viewports while a dialog (such as Sweep2 options) is open.

Unfortunately for me it only happens while plugin has reparented the Rhino window. And this is only on Windows. But it still might be related to the ETO platform that is used for cross-platform compatibility.
