I sometimes see InterBase (6.1.0.6 open) hindering the start of other
applications or even the user logout or shutdown process on Windows NT
4.0.

For example, sometimes when I try to start an application by doubleclick
a file in the windows explorer, this app isn't starting until I stop the
Interbase server. Then it shows up instantly. Another case is that
sometimes (not always) the system is asking me to terminate ibserver
when I try to shutdown the machine.

Any ideas?

Thanks
