Julia v0.7: PyPlot doesn’t work with Atom

Applying PyPlot within Atom stucks in process. I’m using:

Julia Version 0.7.0
Commit a4cb80f3ed (2018-08-08 06:46 UTC)
Platform Info:
  OS: Windows (x86_64-w64-mingw32)
  CPU: Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-6.0.0 (ORCJIT, haswell)
Environment:
  JULIA_EDITOR = "C:\Users\Carsten\AppData\Local\atom\app-1.29.0\atom.exe" -a
  JULIA_NUM_THREADS = 2

with Atom version 1.29 and Julia-Client 0.7.3.

Applying the following lines:

using Pkg

pkg"status"

    Status `C:\Users\Carsten\.julia\environments\v0.7\Project.toml`
  [c52e3926] Atom v0.7.3

  [438e738f] PyCall v1.17.1
  [d330b81b] PyPlot v2.6.0

using PyPlot

leads to a stucking of the last line

Any suggestions are appreciated
