grouped layers not expanded by default

I don't think I had this problem in 10.0 and FW 2.5 but at 10.1 and FW 3.0 I noticed that the LayerList and/or TOC show all grouped layers as collapsed regardless of how I have them set up in my mxd. Basically I have several groups of layers, some of which I want expanded at load to see the layers within that group, and some I want to keep collapsed.

I can't seem to find any way to configure this differently. Any suggestions?

Thanks
