Data Model - CRM Adjusting size of Entity boxes

Data Model - CRM Adjusting size of Entity boxes

(Sorry if duplicate, previous post seems to have disappeared.)

I am viewing the Data Model for CRM, and while it is great to see such a model, there is an obstacle.
Many of the entities show only a subset of their fields. The entity boxes have scrollbars which appear on mouse-over. But I need to see all the fields at once, and also need to be able to make screen shots, which should show all the fields.


So how do I expand these entity boxes to get the full view?  I could not find an affordance or mouse gesture that would do the job.
Thanks.
