The status bar flashes pink (or light red) when Hold Events is enabled. This gets triggered automatically when NMS?receives a certain number of events within a set time frame (the default should be 200 /10 seconds).
Since the default was set lower in earlier versions, it might be set lower on some of your hosts, as an upgrade doesn't change the existing default so please check the IgnoreNimEventsCount key in
HKEY_CURRENT_USER\Software\Nimbus Software\NimBUS Manager\Options\
and change it to a number you find more convenient.
If that doesn't eliminate the problem, make sure you have un-clicked/deselected the 'Hold Events' button/icon on the top of the Infrastructure Manager window and the pink flashing bar will be eliminated. It can be a little confusing since since both Hold buttons (Hold Events versus Hold Alarms) seem to appear alike but one is for alarms towards the bottom of the IM window- 'red light' illuminated in icon, and the other is for Events (messages) - 'yellow light' illuminated in icon.
