Hi,
 If you set the dissalow premature option in the odbc driver it can reduce the
risk of this - but it still does happen and it's extremely dangerous :(.
 I have hacked the odbc driver (for the 7.72.0.5 level) to work with visualage
smalltalk, and have removed the rollback on error with no obvious bad side
effects. (there probably are some though).
