First of all, I've seen the answers which are recommending fiddling with \pnumwidth
and \tocmarg
-- changing these are only shifting the problem elsewhere within the toc, lof and lot.
How can I get no overfull hboxes in the toc, lof and lot (e.g. allow it to be sloppy and underfill)? I've also seen tocloft
package but wish to avoid, as it causes problems with page headers.
