I am using my FB1.5 on win98, during my transactions someone
accidentally unplugged my pc power. Afer restart the pc, my fdb
cannot connected.

I thought SQL DB can protect problem like these to happened. Or is
this a known bug in FB1.5? I had experienced in power failure when I
was using ASA but my db was not corrupted. Can someone explain to me
why FB will have this problem? I thought FB should be intelligent
enough to rollback all incomplete transactions in order to keep data
integrity.
