[NTG-context] figure and table caption numbering

Very original: figures and table captions suddenly appear to all be numbered by chapter - meaning ALL figures of Chapter 1 are numbered Figure 1, ALL figures in Chapter 2 are numbered Figure 2, ... figures in Appendix A are numbered Figure A. Does anyone else notice this, or do I have to come up with a minimal example? (I have nothing special, other than \setuplist[figure][partnumber=no]) Alan
