Hi Ulf,
AFAIK CE databases are managed so as to write as seldom as possible to flash
memory (to conserve the life of the memory as I understand it), so a flush
could possibly write a fair bit of data depending on what has been going on
and could take some time depending on the write speed of the memory. I don't
know of any bugs related to this. I've given up attempting to use CE
databases directly in flash memory in preference to RAM databases with
occasional backups to flash.
Cheers
Doug Forster
