@Trev_lite: what version are you using and what operating system? what options do you have set under the Options->Roles tab? the sorting is getting an overhaul in the next release and this may resolve the issue. i'll still see if i can reproduce it. 'sometimes crashes' isn't really enough for me to go on, more details would be helpful. when you say you can't change the labor, does this mean you couldn't commit the changes? you couldn't click on the cell? were you perhaps trying to toggle a labor on a skill column?
i'm using 19.3 on windows 7
the only bug i could replicate was the sort bug. it ALWAYS happens so is easy to replicate. just in the role tab select group by nothing then click a role to sort by that role then select sort by name then change tabs and come back and it is still sorting by that role not by name. something happens with sort by skill.
for the can't change labor bug (only happened once so far) is that when i click a cell nothing happened. i was trying to toggle a labor for a skill (in the skill/labor tab) it worked for other dwarfs. restarted the program and it was fixed.
another bug is that somehow a row and/or column's separator gets darker like its selected and doesn't go back to normal when i select a different row or column. this has no effect besides looking ugly
only settings different from the default is the expand groups on load and single click to change labors (so no double clicking) and displaying the role for a labor in a tooltip.
hope this helps
