Query is about 300 lines long, editing window shows on first entry after opening KNIME, blanks out entirely at second entry. Eliminate a few lines and the window does not blank out entirely, just shrinks. Eliminate a few more lines and the window returns to normal. Increased memory from 4GB to 6GB, no change in behavior.
