Hi Dojo... since upgrading to a new computer, I'm getting an Unhandled Dispatcher Exception when I try to use the Edit QAction feature of DIS (full error message below). I'm sure I'm just missing some reference or something, but I've been unable to determine what. I'm using DIS 2.32.1.15 which I believe is current. I've trying uninstalling and reinstalling DIS, but that didn't help.

Any thoughts?
