I noticed however, that upon startup the workflow window does not have the usual controls for minimizing, restoring or maximizing the window (see attached screenshot). However, if another window (for example the Node Description Window) is maximized and then restored, the workflow window will suddenly have the resizing buttons.
we resolved multiple visualization issues with KNIME 3.1 Could you check if this problem still exists for you? I personally see the min and max button in 3.1 and Win10
I just upgraded to 3.1 (using the File -> Update menu), but I still initially see no min and max buttons for the workflow editor window. Again, once I maximize another window then return to the editor, the min and max buttons appear. Windows 7 Pro with Service Pack 1.
