This already works correctly. > Nothing in the test case, BTW, does revert correctly to 1.6. Because I only reverted when the glue lengths contain at least a percent length. This is now fixed. Furthermore cases like -2mm+3cm and -1mm-2cm are now handled correctly, see the attached testcase. regards Uwe
