When is suspendStack sent?

[Bob Sneidar]

Hi Craig. No what I am doing is when suspendStack fires, I check a property in the current stack. If it is not "view" I pop a dialog (as sheet) alerting the user thet they have unsaved changes, then I go to the stack (otherwise it will navigate away which is what I am trying to prevent). 

I'm thinking I can use a send in time as it may be that going back to the stack while suspendStack is executing bay be borking the engine somehow. All kinds of nasties start happening, like if I navigate to the script editor under these circumstances, I seem to lose the ability to grad and drop script selections. One time typing in a field actually edited the script!
