We had set R2WinBugs to use the burnin as the adaptive phase. I think this was changed very slightly in the latest version of R2WinBUGS so that the adaptive phase would equal burnin minus 1. This was to allow DIC to be calculated. So I think it should work OK now. If you send an example I can take a look.
