 However if I use just a single dialog box at a time, everything works fine.
 I've used gdk_threads_enter() and gdk_threads_leave() whereever
 possible. these dialog boxes are created on 'select' event of CList so i
 cannot use gdk_threads_enter() and gdk_threads_leave().
 
 I need to have few more dialog boxes, but using only 2 is causing
 problems of application crash.
 Can anybody address this issue?

I didn't really get what the actual problem here is, but some advice
that might help:

* Unless you really, really know that you need to use threads, you
  probably don't... using threads to get basic UI working is almost
  certainly a bad idea.

* gtk_dialog_run() makes the dialog modal, so you can't use several
  dialogs at once. You'll have to connect to the respose signal and
  and show the widget yourself.


HTH,
  Jussi

I don't understand when the problem happens. The sourcecode is not very
specific and it does not explain how two dialogs come into play, since
after executing this code there is just one dialog open.

 I've used gdk_threads_enter() and gdk_threads_leave() whereever possible. 
 these dialog boxes are created on 'select' event of CList so i cannot use 
 gdk_threads_enter() and gdk_threads_leave().

Do you actually use threads?

 of application crash.

I did not yet really understand the problem, I suspect there is a lot of
background information missing.

Bye,
Simon
