I'm running Bitext2tmx 1.0M0 on Mac OS 10.4.11. I just started using it. How do I go about resizing windows. I see the classic two-sided arrow when I'm on the fringe, but I cannot stretch the text windows. Which is kind of a bummer.
You don't resize that version. Get the development version in Git and compile it. That is all that can be done at the moment.
