[v6 General Discussion] After Clicking on ~150 Songs EW6 Stops Responding

I was clicking on songs in EW6 that had backgrounds in my EW2009 database to find the handful that have missing media files. When I was halfway through my list EW6 stopped showing songs in compose pane; last song composed remained in pane. I was not adding them to schedule nor going Live. Several times before it stopped responding briefly and the EW6 program window would go white before responding. The menus drop down but didn't react when clicked on and CPU for EW6 is showing only 7% utilization. Also memory utilization was minimal around 180 MB; computer has 16 GB.

Didn't get errors when starting EW6 every time but still disconcerting to see them because don't know if bad things are happening in background to data.
