I'm using the regex (?<=\d)"(?=\s) to find the quote marks at the end of a number in a tab/newline delimited file. In the find and replace dialog, when I click on Replace my selection is advanced to the next find result, but the previously selected " isn't replaced. My replace value seems irrelevant, I started with no replace value (removing " ) and tried using some random keysmash with no different results.
