Just FYI, on ustar, if you click on full-screen mode with cockpit, the window size seems to flicker by a pixel or two every so often (10s?) for many of the tabs. Every time a window is resized, cockpit erases history. Thus, the effect is to not build up history for most of the dsms. The workaround seems to be to expand the size of the window simply by dragging a corner of the window until the screen is mostly full.
