In horizontal layouts, the minimal width of the editors is determined by their toolbars. If you hide the editor toolbars, you should be able to make the editors narrower.
I meant that I couldn't properly resize the height of the segment editors by dragging the top and bottom separators of the horizontal segment editors.
This went on even after switching between other layouts and restarting CafeTran.
Anyway, after resizing the width of the toolbars, the vertical resizing works again.
False alarm! :-)
With the latest update, I am unable to properly resize the segment editors in these two Layouts. The drag and drop action does not work or results in shrinking the segment editors to an impossible size.
Other Layouts do not seem to present this issue.
Anyone else can reproduce this?
