Normally, when DBM opens he entry mask, the various drop-down boxes with "definitions" from the database are re-read. This can degrade performance over time, especially if there are lots of definitions for one or more fields.
With CacheDefinitions=TRUE, DBM tries to re-use the contents of the drop-down boxes. This will usually succeed, as long as the user stays within the same database server.
Possible values: FALSE, TRUE
