Default Digi 002 Standalone mode problem with digital sync

I have discovered what I can only imagine is a bug in the Digi 002's firmware, and have tried to find any information on this using google and the search feature on these forums, but cannot find anything out there. Maybe someone else who has a Digi 002 can verify that this is happening to them too?

My hardware:
Shuttle XPC (Like the Music XPC) running Windows XP Home (Picture of Computer).
Digi 002 (connected with Firewire and with optical spdif between the computer's optical output and the Digi 002's optical input)
Active loudspeakers

The situation:
When not using Pro Tools I like to use the Digi 002 and its active monitors to listen to iTunes (for WinXP), game audio and other computer-audio.
Because the "wave" drivers for windows do not work properly, I have hit upon the idea to use the 002 in stand-alone mode, receiving audio from the computer via optical spdif and replaying over the monitors.

This works fine, but there is a bug...
Once everything is configured on the 002 (go into standalone mode, change channel 5-6 to spdif, select optical spdif, select spdif as wordclock source, fade up channels 5-6) I have saved a snapshot that always loads with everything set-up. This snapshot always loads when I enter standalone mode. I am aware though, that the wordclock settings are saved with the "preferences" rather than the "snapshot".

Here is the bug:
I have set-up everything as above, I exit standby mode and power-down the 002. When I next power-on the mixer the previous snapshot loads but the sound is aliased and sounds terrible. When I check the wordclock source (in "Utility" - "Pref" - "Wrdclk") it still says "SPDIF", but it clearly is not set to sync from the external source. All I need to do is cycle through the options to "Internal" then back to "SPDIF" and suddenly it syncs properly and everything sounds better again.

I have tried this multiple times and using different startup orders etc, and come back to the same conclusion: that there is a bug in the Digi 002 firmware that stops it from switching properly to external sync on startup even though the spdif option is saved in the preferences.

Is there someone with a 002 that can verify the above, or someone from Digidesign who can confirm that this is a bug (and let us know if it can be fixed)?
I would be very disappointed if I had to reselect spdif word clock everytime I powered the box on.

On a side-note in stand-alone mode whether the 002 is in the bugged state of having SPDIF set but still clocking internally, or whether it is locked to the optical spdif signal, the "48" sample rate button blinks (which indicates a sync error). Using this same optical signal connected to the 002, but running Pro Tools, Pro Tools locks up (at 48kHz) to the optical spdif with no complaints (and a steady "48" light). Therefore there could be another bug in the way the standalone part of the 002 deals with digital sync. It does seem to lockup ok though in standalone mode once you re-select optical SPDIF, even though the "48" light is blinking.

PS: There is no natural place for this post as it is a "STANDALONE" issue with the Digi 002, not a Windows or Mac specific problem, and not really a "host tip" or "host technique". I will post it here, and maybe put pointers in the mac and pc ones.

Any help or confirmation of this bug is eagerly anticipated. Word from Digi that you can fix this is even more eagerly anticipated...
