John/Bill,
this seems to ring an ancient bell...back when the original "free IB" was released end of July 2000, the Windows kit went out with a wrong build of gds32.dll and raised the old bug from IB 5.5 and 5.6, where server events causes horrors to happen...

The workaround at the time was to replace that version of gds32.dll with the (known fixed) one from an earlier build 579. (You can check the version by right-clicking on the file, selecting Properties and looking at the Version tab.)

You might want to give it a try - don't overwrite the one you have in your system directory, just rename it, so you can go back to it if build 579 doesn't fix the problem. If you have IBConsole installed you might want to check whether you have a rogue copy of gds32.dll in its main directory, too, and disable it by renaming...

Here's the link - it's about 360K:
