David,
It makes no difference.
All,
I've confirmed this exists against a stock install. I've opened a bug report (https://openacs.org/sdm/one-baf.tcl?baf_id=1425), and attached some sample code (twice, since I forgot that the SDM doesn't handle html vs. plain text very well).
I haven't had time to debug this yet. If anyone has any idea why this is happening, I'd like to know. Thanks.
