Creating a Modal Dialog from a Routine Called by g_idle_add()

[Marshall Lake <mlake mlake net>]

I've run into a problem with my current project and I'm having difficulty 
finding the cause.  I'm sure the problem is because of a lack of 
understanding on my part concerning GTK.  I'm hoping someone here can prod 
me in the right direction.

I have a routine called by g_idle_add() which updates the contents of an 
already-existing modal dialog with data received from a server software. 
This routine gets called continually until the data from the server 
ceases.  Certain data which is received causes a new modal dialog to be 
created which looks for user input.

Things work fine until a new modal dialog needs to be created.  The dialog 
is created fine and the user input is accepted fine, but I cannot destroy 
the new modal dialog.  And at this point the routine is not called again 
by g_idle_add().  The program hangs, and the only thing I can do is kill 
the new modal dialog which in turn kills the whole program.

Can someone clue me in to what might be going on?
