I have a fairly simple workflow with a few nodes. I’m unable to remove and existing connection between any of the nodes. The delete button works, but the old right click method doesn’t.
@rfeigel I think the version 5.7 was released somewhat by accident and the (new) default WebGL rendering is not ready. You might have to switch back to KNIME 5.6 unfortunately. 5.7 seems to be due end of September.
Thanks for reporting. I can reproduce and opened a ticket for the developers (NXT-4071).

@nan since you are at it. Links in workflow annotations also do not work with WebGL in 5.7.
That’s really frustrating. I didn’t install 5.7 separately. It was pushed through my existing 5.6 installation which now of course is gone. I guess I’ll have to reinstall it manually.

@rfeigel I know. It was offered as an update and I was excited and clicked … and now I have to re-install 5.6. Just got a newsletter that announced 5.7 for the 8th of September. So we will have to see what will happen.
Afraid that @armingrudd confirmed this in our stars association meeting with the devs… must have been available just for a short period of time by accident…
