Oh dear, sounds like a pain in the proverbials.

Any clues on how I could go about tracking this down or somehow bypassing it?

Replace all ICs that directly connect to the address lines?

As it's only exhibiting itself during Fluke tests and can then be
circumvented by grounding the watchdog disable point it doesn't sound like
that big a deal, BUT I have a feeling that it might well also cause random
problems during 'normal' (ie non-Fluke) operation ..........

Thanks
