Hi, HB (don't want to call you HalfBaked, that would be rude
):
Unfortunately, this is a long-standing issue that I thought had been pretty well cured in latter releases.
It is, in fact, much better than in earlier releases.
The best way to minimize the issue is to be very careful with your note entry, meaning be sure you separate each note when 'playing' them. Don't try to do step-time entry at a real-time tempo; you'll get spurious rests.
If you are slow and careful, I think you'll still have a few corrections to make every few bars, but not enough to drive you to drugs.
Hope that helps.
David
