I'm not sure how I'd investigate such an issue.
And I'm also swamped :)
I don't even know what ADO is so I doubt if I'd be much help.

scot.

Hi Scot,

Unfortunately I've been seeing some unexplained errors with some
Microsoft ADO based apps since applying this patch, so I've backed it
out for now. Unfortunately, ADO doesn't give any useful error messages.

I'm not entirely sure what's wrong - can you look at it please? I'm
still swamped at the moment :-(

Regards, Dave
