It sounds like the threading problem that was happening with early versions
of the IB 6.0 client program (gds32.dll) with events. When you posted this
message elsewhere, I asked you to check out the version codes on gds32.dll
on the problem machines but you didn't respond to that.

You should also search those machines for rogue copies of gds32.dll that
might be hanging about from old installations, and rename them. (Some
installations of IBConsole offend in this way by storing a copy of
gds32.dll in the same directory as the exe).

For RC2 and IBO, your gds32.dll needs to be in the system directory
(\System32 on Winnt versions, \System on Win98) and its version string
should be "WI-T1.0.0.679" (the final number [build number] could be higher,
but it should not be lower) and it should not be an InterBase version code,
e.g. WI-V6.n.n.nnn
