Thanks Mark that did the trick. I should have known to look in the error handler class...

Hi John,

If you look in TempHire in the ErrorHandler class you will see it checks for TaskCanceledExceptions and simply ignores it. This way you don't have to write try/catch code everywhere.

So I am still getting used to the new DevForce/Cocktail stuff. One thing that has been happening is that when a user clicks cancel on a dialog the Task throws a task cancelled exception. I read somewhere to handle cancelled tasks with a try/catch. I did that twice and realized that was bad advice. I have too many dialogs and I am not about to litter my code with try/catch blocks. 

I looked at the temphire app and I didn't really see how it was handling the cancel. I am guessing it is in how you implement it. When I implement it this way:
await _DialogManager.ShowDialogAsync(vm.Start(ServiceInstance.ID), DialogButtons.OkCancel);
 I get exceptions. What do I need to change?
