Update 2/10: This issue appears to be fixed in 2012 R2 UR5.
A while back I ran into an issue with creating some dashboards for SCOM. Specifically, the issue came along when working with the Alert Widget. I ran into the issue where columns in the Alert Widget would get very wide and one column could fill up an entire screen, rending the rest of the view essentially useless. This is due to the “Auto” width feature in the widget. While it is great to have Auto as an option, it isn’t always appropriate for all columns.
