We just switched to the new editor today, and ran into several issues...
1) Closing quotation marks are marked as error. Opening quotation marks are in segment X, closing marks are in segment x+2 -> marked as error.
2) leading spaces before single quotation marks are marked as error. Correction leads to loss of space between word and quoatation mark (Segment 8-4)
3) leading and trailing spaces are marked as error.
