(This makes me wonder if I can work more easily on a slower machine — my PC’s pretty fast and is sheer hell to reconcile budgets on, while my work machine’s slow but is super-easy to do CalendarBudget on. Note that if a machine fails, it’ll fail on ALL browsers: Chrome, IE, Edge, Firefox, Opera.)
Is it possible, I wonder, that there’s some CSS flag on the ‘transaction’ that will make the dragAndDrop not think I’m trying to drop the transaction on itself?
I think this is a DOJO “bug” — some obscure problem caused by the port to the more recent version of Dojo.
