Dialog boxes in seperate thread

["David Conley (FRD)" <dconley frd co uk>]

Are modal dialog boxes possible in threads? I have this call in a thread 
seperate to the main gtk thread:

gtk_dialog_run(GTK_DIALOG(errorDialog));

and obviously that locks that thread while the main thread continues but 
nothing updates the display in the blocked thread and the app becomes 
unresponsive.

Any tips appreciated.
Thanks
