In 10.7.5, that separator went away, which is fine for files that have a short path from the left-most column to the right-most column. You can still grab the side of the window and resize the last column. But for files with long paths (which introduce a horizontal scroll-bar), it sometimes becomes impossible to resize the last column. So here's a simple work-around.
- Grab the right-most column separator (which is to the left of the last column) and drag it to the right, making the second-to-last column as wide as you want the last column to be.
- Scroll all the way to the right
- Grab the same column separator and drag it back to where it was. (Note the preview size does not grow when you do this.)
- Slightly adjust the height of the finder window from the top or bottom and your preview will snap to the largest possible size to fill the space.
[crarko adds: I don't have 10.7.x around any more to try this, but it didn't seem to be an issue in 10.8.2.
Hi, all! Kirk is out this week so I am filling in in his absence. Nice to drop in, although I'm trying to remember all the little BBEdit shortcuts we use here, so please excuse me if things are formatted a bit oddly.
