+I am running _WSJT-X_ on Linux using a KDE desktop. Why does *Menu->Configurations* misbehave?::
+
+The  KDE  development  team  have  added code  to  Qt  that  tries  to
+automatically add  shortcut accelerator keys to  all buttons including
+pop up menu buttons, this interferes with operation of the application
+(many other Qt applications have  similar issues with KDE). Until this
