When working in the Contacts section of the UI, it becomes unresponsive after a series of steps. This can happen with both IE and Chrome. Steps to duplicate:
- Click on the Contacts tab.
- Scroll through 10-20 contacts using the mouse wheel.
- Click on the Search box, type a common name, and press Enter.
- The little box at the top next to Contacts shows [N] found, but nothing appears in the list. Trying to clear the search or clicking Actions or View does nothing. Other tabs like Email continue to work, but the only way to fix Contacts is to logout.
You might have to repeat this process 2-3 times as it's somewhat inconsistent. I found it easier to duplicate with hundreds of contacts (most were imported from Gmail, but not sure if that matters). Also, you don't need to use the mouse wheel (#2), but it seems like you do need to go through a few contacts with mouse/keyboard.
