Thank you very much, Robert, for this quick solution!
Yes, replacing MinimumPosition with ReferenceWidth in the header item
seems to have solved the problem.
Though I haven't run all my tests yet - only the one file.
*And do I understand you correctly that it is safe to change this for
all versions prior to v0.66 as well?*
Or let me put the question the other way around:
Is it really necessary to introduce incompatibility here?
All scripts that use .MinimumPosition from element 0 won't work anymore.
I have never noticed that MinimumPosition could be replaced with
ReferenceWidth, because storing in MinimumPosition updated the value in
ReferenceWidth too - for whatever reason.
I understand that it may be more clear to use ReferenceWidth directly.
However, it has worked fine so far in previous versions.
According to the new documentation "SetMinimumPosition can't be applied
to the init beat chart element".
So if MinimumPosition is not used in the header element anyway, then it
could still be used just for compatibility reasons.
Currently I have only updated the Perfect Layout code. But I'll have to
check the other plug-ins too.
I ask because the fix is a bit risky.
When updating the code you have to make sure only that only the 0-index
elements are affected and not the elements above index 0.
