Why does SolidWorks release a Service Pack (SP 4.0 for 2010 64 bit) that greatly reduces their product's functionality? When you open a design table within SolidWorks you get all the functionality that SolidWorks has always offered. When you open a design table in a new window, SolidWorks functionality is virtually gone. You cannot even measure with a design table open in a new window. Forget trying to select a new configuration or even open a sketch to select a dimension. I've reproduced this problem on two different workstations. As you all know, working with large design tables often requires using a new window. Is this an undocumented design feature (aka BUG) or is this intentional?
