Version: KNIME 3.1.1 (also happened on 3.0, but not 2.x)
Platform: Mac mini & Macbook air, OS 10.10.5 (Yosemite)
Since upgrading to version 3.x, typing in the Node Repository search box often slows down KNIME (unresponsive); the colored spinning Mac symbol appears. Mostly KNIME recovers - it just looks and feels bad; but sometimes KNIME will crash (losing all work since last save), and in one instance the whole OS became unresponsive and I had to hard reboot.
This did not happen in version 2.x.
It happens both when a workflow is executing or not.
I couldn't see where to log bugs so I hope this is the correct place.
There used to be a config flag which would require an explicit "enter" press to execute the search, rather than the current "search as you type" - anyone remember this?
