Error when using ElectronDisplay's Table display

[realkrantz]

This works:

using VegaLite, VegaDatasets, ElectronDisplay
dataset("cars") |> @vlplot(:point, x=:Acceleration, y=:Miles_per_Gallon, color=:Origin)

But this does not work:

using DataFrames, ElectronDisplay
df = DataFrame(a=rand(100), b=rand(100), c=rand(100));
electrondisplay(df)

Error message:

Please help

While I did not preproduce the same error, when I tried the second example, all I got was a blank window.

it turned out to be that running the second command required Administrator privs to create the named Pipe.

Although perhaps a more fine grained solution would work
