Here is one i have never before seen: At the end of one system, the bar line is placed before the staff lines end. All the other systems have bar lines at the end of the system. Usually, you can grab the handle of the bar line and move it. In this case, it will not move.
Below is a screen shot. I would include the Finale file but do not see a way to do that.
Finale 2014.5 (i won't upgrade, because they deleted BIAB harmonizing in later editions.)
Windows 7 pro, 64 bit (i won't upgrade, because Microsoft now requires a monthly fee for something i already purchased.)
