a little bug on my opinion. Take a text file and try to open it with file reader node. Click on advanced. Change the character decoding to something else than UTF 8 or ISO-8859-1; type OK. Knime blocks then type cancel. Knime remains blocked.
Knime version : 2.12.1
thank you for reporting this. We did fix some things for the CSV Reader in 3.1. and I could unfortunately not reconstruct your bug report.
Could you validate, that this is still the case with 3.1?
tried with the 3.1 version the same problem occurs. I have to to alt control delete and restart Knime.
