Since I've identified the current problem is stemming from setting the menuPost
resource, Alexander pointed me at this little snippet from ddd
if (XmVersion < 1002 || lesstif_version <= 84)
{
// Setting the menuPost resource is required by Motif 1.1 and
// LessTif 0.84 and earlier. However, OSF/Motif 2.0 (and
// OSF/Motif 1.2, according to Roy Dragseth
// <[EMAIL PROTECTED]>) choke on this line - buttons become
// entirely insensitive.
XtSetArg(args[arg], XmNmenuPost, "<Btn1Down>"); arg++;
}
It seems that they have determined that the menuPost thing is no longer
necessary.
