Exceptions while running a dialog box

[Ari Jolma <ari jolma tkk fi>]

Hi,

I've got dialog boxes, with which the user may interact and which are 
modal. In some cases the user requests something that does not work out 
and that causes an exception. In my current implementation this is a 
problem since the dialog box stays visible but not working. There are 
two possibilities: close the dialog window (from the X at up right) or 
"open" the dialog from the main window again. The first one destroys the 
dialog and it is not usable any more (the dialog is created from glade 
XML and used like this: show, run, hide) and seem to cause problems when 
the program is closed.

What would be the best solution for this kind of case? All I can think 
is to get rid of or avoid croaks.

Regards,

Ari
