More information, please; if possible, provide a screen shot. Make sure Show Invisibles is on, as well as Show Guides. Screen shots can be inserted in your post using the camera icon in the toolbar.
"Blank space", is that horizontal space (i.e., tabs, em-spaces, or 'empty space' such as on the right hand side of ragged right text) or vertical (such as extra space between lines or paragraphs)?
Sorry, my details were rather terse. Blank space is empty (white) space at the bottom of columns where the text should fill the complete height. It did initially, but after I adjusted the height of the 3 columns on the first page, the second page went wonky. I dragged cols 2 and 3 on p1 down flsuh with the text of col 1 (probably not the recommended method), and the header still looks dumb stuck over in col 1. I know all these issues only reveal my shortcomings. Hopefully the screen shots will show what I haven't explained.
Well the camera lets me select a file, but the Insert Image button is greyed out, so no joy there either.
Ha. I had to save it as jpeg. Png files don't work. Above is p1.
I don't know why it's breaking the way it does, but I see each entry is followed by a non-breaking sapce, then a tab, then 2 spaces. Why not just use some combination of fixed-width spaces, say 2 or 3 em spaces, to get consistent spacing?
It seems the problem occurs with Level 2 or Level 3 entries only. Can you check if one of these have a Keep With Next Paragraph setting applied?
(Actually, if that *is* the problem, I would expect your Index Level 1 to have a "Keep All Lines Together" as well. Perhaps that is set in your "No Paragraph Style"?)
I don't really think it's a keep option. The last entry on column 1 is split across columns on page 2, and it looks like there's enough room for any imaginable keep.
@ Ebeneezer, IS ID patched to 7.5.3?
Sorry for the delay with responses, but it's a time difference being in NZ.
It did turn out to be a Keep With issue. Index level 2 had Keep With Previous ticked, and when unticked all behaved again. Many thanks for all the suggestions. I'm just relieved to have found the solution after all.
Yes, I am running v7.5.3.
