KNIME crashes upon confirming node settings

I'm carrying out some simple molecule .sdf filtering tasks with KNIME, and the software was working fantastically for the first few sessions. However, the software is becoming almost unusable, as it crashes at will when I confirm or apply node settings when configuring. Has anyone else experienced this problem using KNIME on a mac?

Hi. Do you find any hs_err* files on your file system? Search in the 'Search' bar on any Finder window.
