You could try using a modal sheet, if it fits your modal requirements:
// show the save sheet
[NSApp beginSheet:[self window] modalForWindow:_modalForWindow
modalDelegate:self
didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:)
contextInfo:NULL];
I use such a configuration and my app continues to receive events from my run
loop attached network sources.
