Can't Resize Operators

I have a problem with operators, I cannot resize them.
It’s not a big problem, but with CHOPs it makes me have to zoom really far in to drag and drop, did I accidentally toggle something?

We haven’t see this happen before. Are the Viewer Active flags turned on on all the nodes? Perhaps a screengrab would help us understand.

As an option, you can right-click on any operator and select “View” to get a floating window of the operator to work with.
