my Knime installation doing something very strange: If I double click on node, it will not open. If I right click and choose configure it will display a virtually empty box. It does that for all nodes including metanodes (that though open when choosing metanode open).
I run Knime in the version 4.2.2 (and the older 4.2.0 has the same problem) on Opensuse Leap 15.2. It did work a while ago - in fact I created the workflows on the very same machine and Knime version. If I reset my system an older system-configuration it still does not work.
What do I do wrong?
Help highly appreciated
