[NTG-context] reference problem

Hi all, I have a problem with references to equationnumbers. Let \the\equationnumber be 1. If I type \reference[a]{(\the\equationnumber)}$$ (a formula) $$ \advance\equationnumber by 1 \reference[b]{(\the\equationnumber)}$$ (another formula) $$ ... \in[a],\in[b] ... I expect to get "... (1),(2) ...". With an older version of Context (2000.12.14) this works fine. But with the new version (2002.10.23), I get for both equation a and b the same number (namely the last, 2): "... (2),(2) ...". Is this a bug, or has somewhat changed? With many thanks in advance Albrecht
