Bugfixes

The 6 November updates dealt with three quite severe bugs. Two were in the fundamental data structures in the Pyrrho data engine - indexing and multi-level indexes, and seem to have crept in at different stages, fairly recently. They weren't detected in routine testing. An unrelated query processing problem was just days old, and should have been spotted.
The Embedded edition is temporarily unavailable because of a different problem.
Please send in reports any time you find anything incorrect.

Updatable RowSets

Today's update fixes a number of issues with the updatability of RowSets. The basic idea is unchanged: a RowSet is updatable if is has been selected (via a view or directly) from a single base table and its columns include the primary key. Unfortunately this simple idea got overlaid with PyrrhoMgr trying to be too clever.
