UndefVarError: setexcludinghandlers! not defined in Jupyter

[treygreer]

With a fresh install of ulia 1.7.3, Interact, and Anaconda3, I get the following in a jupyter notebook:

using Interact
foo = slider(1:10)

The first time I try moving the slider I get:

KERNEL EXCEPTION
UndefVarError: setexcludinghandlers! not defined

Seems this might be a WebIO issue: JuliaGizmos/WebIO.jl#493

Never mind, I was led astray by a rogue Project.toml in my windows home directory. Sigh.
