ZEO and COM

[drs]

please let me know if there is a better place to post this ...

I am trying to create a shared dictionary which can be accessed via COM.  To
that end, I have written the code below (at the end).

So far this works from a single computer, but if another computer tries to
share the data it is unable to see changes, and throws exceptions when it
tries to rewrite data.

Does anyone know how I can make all connections aware of changes?

Any ideas?

Thanks

This is w/ ZODB3 3.1.2, Python 2.2, win2k
