Can this be a an issue where the GUI is receiving CA monitor events
directly and focusing the associated window with each event? If so, can
you throttle widget updates in Winteracter to a fixed interval rather
than updating the GUI for each CA monitor event received?

I’m seeing a conflict between:
“medm pilatusDetector.adl” and a Winteracter program. Winteracter
creates GUIs for Fortran programs using Motif. The Winteracter program
is simply waiting for input while the problem occurs. The result is that
input focus shifts rapidly between two Winteracter windows. The medm
windows do not get input focus, so it’s hard to understand how medm
contributes to the problem.

What are the GUI applications involved?

I’m running an application on a Linux x86_64 machine which opens several
windows for user input and data display. It runs fine unless I have an
EPICS areadetector IOC running in the background, in which case I get a
“focus deadlock”, where focus shifts rapidly between two application
windows and the screen becomes unresponsive to keyboard or mouse input.
The problem occurs under Gnome but not KDE. Running KDE is an effective
fix, but it would be nice to get to the bottom of the problem. Can
anyone suggest what’s going on?
