Hi Naomi.

>When I try to see (and set) data groups the table belongs to, I can not. I try to open the combobox, but it automatically closes and doesn't display the information.

That's a bug I just discovered myself and fixed last week. I'll post an updated version later this week. In the mean time, you can still see which data groups the table belongs to -- they're displayed as comma-delimited names in the combobox -- and change them by going to the Data Groups node and changing them there.
