Mark,

>The components aren't much use to set active at design time.

I am sure you are right about this and the quirks.

I was just setting the active property to see what happened; but when
I got the GDS32.dll error I was confused.

I did, immediately, look to see if the component required a Connection
component; but, as there was no such property, I assumed that was not
the issue.

Thanks again,
Clive.
