1071 doing the equivalent C code does work, with the notable disadvantage that

1072 the user can't override it. So that's what we do until we figure out

1084 /* This is a kludge to disable drag-and-drop in dialog boxes. The symptom
|
|
|
1085 was a segv down in libXm somewhere if you used the middle button on a
|
|

1086 dialog box to begin a drag; when you released the button to make a drop
|
|
|
1087 things would lose if you were not over the button where you started the
|
|
|
1088 drag (canceling the operation). This was probably due to the fact that
|
|
|
1089 the dialog boxes were not set up to handle a drag but were trying to do
|
|
|
1090 so anyway for some reason.
|
|
|
1091
|
|
|
1092 So we disable drag-and-drop in dialog boxes by turning off the binding for
|
|
|
1093 Btn2Down which, by default, initiates a drag. Clearly this is a shitty
|
|

1094 solution as it only works in default configurations, but...
