2) There is a more subtle ongoing problem that (as far as I know) has only been reported here at Jefferson Lab. When an EDM session has been left running for a long (variable) time, the widgets will stop updating despite the fact that the PV values are still changing. There is no visual clue that anything is wrong, unless you can see the same PV's in a different app or a separate EDM session. Usually everything will start updating again if you open or close a display, or even expose a covered display. This issue only started when we moved from HP-UX to RedHat Enterprise Linux. It has not yet been resolved.
We here at the UW Medical Center have also seen this behavior, running EDM on Debian Linux.
