Hello, this is more of a bug report but it would be nice to receive a solution if you figure it out. I installed Knime 2.12 some time ago and had a workflow where this Document Viewer worked fine. Now, the same Document Viewer crashes Knime (it just closes instantly with no warning and whatever state I was in is not saved) when I click on one of the documents to view it . FYI...
thank you for reporting this problem. This is a Linux gtk issue and can be avoided by adding the following two lines to the knime.ini before the vmargs.
It is important that the two lines are before the vmargs and that thw value 2 is in a separate line.
