I get this (see attached) when I first open many parts. Not all of them do this, but I’m guessing 60-70% open like this.
The only way I’ve been able to fix it so far is to show signposts in Write Mode, filter/select them all, and hit Delete. So far, that has worked for me — I instantly get a reasonably laid out part that with a little tweaking is acceptable.
Is there anything I’m doing to cause the mess in the first place, and is there an easier fix for it once I have it?
There has to be one of those signposts forcing all your score onto one page, hence deleting it allows the score to flow properly. Perhaps if you share a sample file someone can diagnose exactly what is going on. Sounds like everything was forced into one frame.
This is something I have had sometimes, when deleting the wrong Page break signpost… Then I had to delete them all in order for Dorico to do its job better, and then tweak as I liked… Now that we have the filter option, it is WAY easier to delete those breaks in one step !
Yes, it has happened to me 3 or 4 times as well… It was always a wayward system or frame break that was the culprit. My first instinct was to panic but when I spotted the problem and deleted the forced breaks and reopened the project all was well.
