The background images for OpManager are too large, causing very poor performance over RDP.  When accessing OpManager over a remote RDP session, it often hangs the browser for 30 seconds, while the background image is redrawing as it fades in.

This makes it very difficult to use OpManager over a remote RDP connection.  Needless to say, this is frustrating during an outage scenario.
