Is the Winteracter program using EPICS Channel Access, or is it a non-EPICS application?

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?
