When I set a Yes/No variable via a dispatch script to 1, its associated checkbox seems to update fine.

However, a transition in a workflow stops working because the value is no longer Yes or No.  Dispatch won't let me set that variable to 'Yes' or 'No', it wants a value.

Any ideas?  Is maybe the non-zero value need to be something specific (like 0xFFFFFFFFFFFFFFFF) ???
