Thank you so much for replying. I posted more details in a stack overflow question since my question was not showing up here.
The behaviour is: - the editor shows a red line above each occurence of #%% - press Ctrl-Enter in any cell N - console shows runcell(0,... - the whole file runs as if no cells were defined Everything is installed using conda spyder 4.0.1-py37_0 --> 4.1.2-py37_0 spyder-kernels 1.8.1-py37_0 --> 1.9.0-py37_0 It's very puzzling on top of being annoying!
