Ed,

Have you tried changing your code to execute sql using IBOQuery instead
of using the connection component? Maybe it's only through there that it
causes this problem. I've had an embedded version running for years and
haven't ever seen the problem but I use a regular SQL component and query
using 'Select Gen_ID(gen_name, 1) from RDB$Database'.

Don't know if you've tried this to isolate the problem or not, just thought
I'd suggest it.
