Open the "define new multilevel list" dialog box, and assume that you have
the "add tab stop at ..." checkbox checked at level 1 and 2. Select level 1,
uncheck the add tab checkbox, click on level 2, uncheck the add tab checkbox,
then select level 1 again. The add tab checkbox will be checked! Is it my
fault or is it a bug?
PS.: if you click OK at each change, it works, but if you try to modify
multiple ones, it doesn't.
