OK ,

I've reproduced this on the 1.7.0 VM and my new 1.7.0 clean installation, both with the demo data provided ( both using UNIX with Oracle ) . Replicated issue with the latest versions of : Chrome, Safari and Forefox .

Follow these steps to reproduce the issue:

- Log into webclient with demo user account.
- Navigate to the term Demographics -> Gender -> Female ( don't think term matters ) in upper left "Navigate Terms" area
- Drag over the "Female" Term into the first "Group 1".
- Select the "Run Query", take the "number of patients" defaults on the pop up and see results in the Query status box below .

Ok , that all works great . but ...

- "Select the "Clear" button , ( notice that everything on the right shifts down and their is a "New Event" section near the top of the screen. )
- Select "Male" form the Term area in the upper left and drop it in the "Group 1" area.
- Select "Run Query"
- At this point the query status is not updated and no results ever return to that box.

One can mass around in and set the "Temporal Constrain" to treat all groups independently" in order to get back in a working state , but users should not need to do that to get the search to work.
