Here is a google chrome bug I logged with MS connect.
Make sure you expand the reproduction steps, but here they are again:
- Using Google Chrome: Open up central administration
- Navigate to : Central Administration > Site Settings > Term Store Management Tool
- Try and select a Term Store Administrators . For example, manually type in "administrator".
- Wait for cursor to refresh
- Notice the box clears of any input and anything you typed is lost.
If you can reproduce this issue, please support this bug to get it fixed.
