Upper-voice-dotted 2nds positioning issues
The 2nd between the soprano E and alto D, the alto D is positioned too far to the right, causing the following problems:
The D can be selected and Chord X position changed to about -0,60 to correct the problem, but very often simply clicking the lower note (here D) causes MS to hang with a spinning beachball (Mac) and MS must be force-quit and restarted (hence issue reported as S2 Critical, although the hanging is random, not always, it happens more often than not).
The note following the wrongly positioned note, here the C following the D, cannot be moved to the left. Changing the value of Chord X for the C to a negative value doesn't move it closer to the D, instead it pushes itself and everything left of it to the left, and the spacing remains the same, the measure just gets wider which makes the spacing even worse. The spacing of the 8th notes in the alto looks wrong, and the problem is emphasised by other voices aligning with the D and C, here a tenor voice G# and A. The alto C and tenor A need to move left, but MS apparently makes this impossible. I guess this has to do with automatic placement, but could not find a switch on any element to change this behaviour. I did not open a separate issue for this because it seems to me directly dependent on Problem 1.
The far-right position of the alto D is apparently being calculated as if the dotted upper voice soprano were on a space, as below:
In this case, the spacing is correct, although the alto E is too far to the right and cannot be moved left (see above). MS is erroneously applying this wide spacing to the lower voice for all upper-voice-dotted seconds, resulting in the above explained problems.
