Using seadasva54 in a laptop with 1200x800 pixel display, large widgets don't get a scollbar, so it is not easy to get to the bottons at the bottom.  I normally run the VM in fullscreen.  If I switch to a window, the VM resizes the display to fit the window, and I don't get windows scrollbars.  If I then use the ubuntu randr widget to set the virtual display to 1280x1024, I get windows scrollbars and can scroll down to reach the buttons, but I would prefer to be able to stay in "fullscreen" and have scrollbars in the SeaDAS widgets.  There are also some problems with tiny fonts in firefox, etc., that I suspect stem from the way the virtual display is resized.
