Yes, sorry, the context got lost somewhere up-thread. I definitely would 
prefer to use gtk_dialog_run(), but unfortunately I have two windows 
that I'd like to be independent, and from what I gathered from this 
discussion, I can't use the function in that case.

Thank you, gtk_window_set_modal() is the answer! It's not that simple, 
though. I had tried gtk_window_set_modal() before, but it had made both 
of the windows inactive.

Since you mentioned the function, I decided to give it one more try. 
This time, however, I put the windows into separate window groups and 
that worked like a charm.

The documentation for gtk_window_set_modal for version 2.19 says:
> Modal windows prevent interaction with other windows in the same

It would probably be better if it said "in the same window group", that 
would have led me straight to the solution.

I had tried that as well, but it grayed out the controls of the window 
(which is undesirable) and the window still responded to the close button.

Thanks again,
