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

[Subrata Dasgupta]

Hi All,
I have a legacy UI application written in C++ using Xt and Motif libraries. But while closing a window the whole application stuck for around 30 second. After debugging I found that application is hanging within XtDispatchEvent() function after finishing _XtDefaultDispatcher() call. 

What can be the probable reason of this problem? I do not have much experience in the Xt or Motif libraries. Please help. 

Thanks
Subrata
