itkwidgets: ITK Widgets not displaying in windows 7 machine

Hello,

I’m trying to use the command view of itk widgets as follows:

from itkwidgets import compare, view compare(fixed_image, moving_image)

And i get the following result:

i.e. the images do not show, but the interface seems to be somehow working since the cmap and gradient opacity buttons are working.

I’m currently using a windows 7 machine and google chrome. In another windows 10 machine I can run the same code successfully.

Could anyone please help me?
