Re: Xt / Motif C++ application hangs in the XtDispatchEvent call

[Subrata Dasgupta]

Hi ,
Thanks for the quick reply. 

It is a 32 bit c++ UI application written long before. I do not face problem in most of the cases. Face this hanging problem only for 2-3 windows, other windows are working fine. Below are the versions of library and the platform used.

Platform         - 64 bit Red Hat Enterprise Linux Server release 7.2 
Xt Library       - libXt-1.1.4-6.1.el7.i686
Motif Library    - motif-2.3.4-7.el7.i686 
X11 Library      - libX11-1.6.3-2.el7.i686

I am not sure whether /usr/bin/Xorg is the Xserver . But the if it is the Xserver that you mean then below is the version..

X server -  xorg-x11-server-Xorg-1.17.2-10.el7.x86_64 (64 bit)

What can be the probable reason for this .. Please help.

Thanks
Subrata
