Split measure results in 2 measure rests
When you split a measure before the current note (in the edit|measure menu), the result is 2 measures with measure rests in them. I think that the normal result should be to fill the measure with appropriate rests.
I changed measure 3 in the oboe to a 1/4 rest to show what is actually happening.
This worked in several measures I tried. Has this been previously addressed?
