IupLua5 is still beta, it is not handling errors correctly. IupLua4
shows a small dialog with the callstack and everything.

You are looking for a message loop. You should call IupMainLoop().
This will run until all dialogs are closed (or until you return 
IUP_CLOSE in any callback).

If you would like a modal dialog, just run IupPoup instead of IupShow
(IupPoup will run a message loop for you and will only return when
the dialog shown is closed) - this will give you the same result as
while dialog.visible, but will not consume as much CPU.
