Yes: that's it.

As for special circumstances, my installation is as simple as it could be: just AC3D plus the X-Plane plug-in files and the two text files from X-Plane 10.51 (see above). That's it — and yet on my computer the pulldown doesn't work.

Other pulldowns, such as the one to select the manipulator type, work fine. When I click the one to enter a dataref, first nothing happens. If I click it a second time the computer makes a warning "purr", places a flashing cursor in the dataref entry field, but otherwise does nothing useful.

It makes no difference whether I delete any text in the entry field before pressing the pulldown button.

I've dropped back to AC3D 7.5.02 with the 3.3.0b1 plugin for the time being.

Guy.
