When typing scripture reference use Tab to move to next field, e.g. Exo, Tab, 3, Tab, 3-7.This makes sense of course, I just need to retrain some muscle memory.
I do for scripture but don't for songs, I like to be able to vary font size for different songs and different parts of songs.
A default scripture theme will set the Font attributes and background. This is especially useful when specific attributes are required.
I ctrl V from copying song title from Word 2010, that's been my workflow for years with EW2009 and then to EW6, bit annoying to select the title box in editor, have cursor flashing there and then to have pasting occur elsewhere. Hopefully being fixed.
The Ctrl-V behavior occurs on first action after starting edit. Click somewhere in song allows paste to work properly; also Shift-Insert not affected by this bug.
The font size drop down selector's behavior has changed, both schedule and resource editor versions. It no longer reacts to selections. The bottom two related auto sizing will show selection but it doesn't close after selection. Font sizes don't remain selected, typing in size only way to be certain correct size is applied.
My themes don't appear to have been affected, I don't use presentations and Access Violation errors.
Have you tried using the import option in the song editor? It might be able to import the text and format it properly without the copy and paste procedure you are going through.
The issue with the font sizing drop down has been fixed in 6.3.1, which was released today. 6-22-15
