Re: Beta 2.08 : Dots placement - Newly discovered buglet
NWC2 places two separate dots for the same pitched note. This appears to be wrong and, at the least, confusing. Prior to 2.08 NWC2 and in NWC1 a "doubled" note that was dotted had the dots overlapped in the same spot so that they were indistinguishable from each other. As a musician, this is what I am accustomed to seeing in orchestral and band music and in church hymnals.
Your example is exactly what you will find in the Official Hymnal of the Protestant Episcopal Church of the USA. 1940 edition, printed in 1961. Presbyterians (1933), OTOH, place 1 dot, sometimes below, other times above, Methodists (1964) place 1 dot above. Look at the tune: ITALIAN HYMN in your favorite hymnal.
In the beta newsgroup, in topic: "Misplaced dots after dotted notes", I posted an example (Episcopal 349 - 350.tif.jpg).
In the same thread is: rg_Dots02.nwc, 35 examples of how G. Schirmer handles dots in chords containing a second.
This code fixes your 1st problem. The half note would need a layer (I think).

The fix I am using is to put the dots in as text when I don't like NWC2's. My font editor is my friend.
