Also, Engaver Spacing is saved in the preferences file. So if you have a preferences file that you saved and then load in ocassionally, Engaver Spacing could be turned off in that preferences file. If so, just turn it back on and resave the preferences.

Using different preference files could explain why some songs show problem and others don't. I can't find any other settings that happen to also turn Engaver Spacing off as a side effect. Returning to Factory Settings will turn Engaver Spacing on also.

And again though, this is with 2011.
