Dear Bugfixers,
I have the following problem:
Symptom:
When I try to select an item (by mouse or keyboard). It gets immediately
unselected. It is impossible to copy/paste text out of ddd and (much more
worse) it is impossible to select any DisplayNode in the DataWindow. When I
try to select a node, it flashes up for a short time and the node keeps beeing
unselected. With that behaviour it is not possible to work with the
DataWindow
Analysis:
I did a little debugging and could trace down to a specific callback function
in the file DataDisp.C (line 7009) The last line of the DataDisp
constructor:
XtAddCallback(graph_selection_w, XmNlosePrimaryCallback,
SelectionLostCB, XtPointer(0));
when i comment it out, at least the DataDisplay seems to work fine.
Of course this is not the solutions of the problem: I still cannot select
any text, in any other view. But it seems that some code forces all widgets
to loose the their selection.
Environment:
I had this behaviour on all the following systems:
Debian (stable, testing, unstable), Redhat 9.0 and cygwin.
I am wondering that I never found something about this on the web.
