IOBox empty spread bug

as the GDI text uses much CPU power, we decided to use ampops ScrollBox for browsing in our videosampler.

works fine, but i noticed a bug in IOBox (Value Advanced).

reproduce:

make IOBox (Value Advanced) and switch sclice count mode to maximum, then connect an I (Spreds), or whatever you want to make an empty spread, to one of the inputs. if the input is an ampty spread, the IOBox will stay forever in this state …

or do i misunderstand the maximum mode ?
