I would like to report a kind “cross-talk” between Knime and the Chromium browser on my Ubuntu 18.04 machine. Sometimes Knime completely freezes; after I close my Chromium browser window that I use for unrelated stuff like gmail Knime immediately becomes responsive again.
It could perhaps be a memory issue, but it does not look that way because all other apps that I have open continue to behave normally. If it happens again I will post a response to this post with the memory situation.
Perhaps relevant info from the Knime preferences:
My default system browser is Firefox.
