Thanks Tim,

You are more than welcome. ;-)

Looks straightforward enough.

Hmm ... I have to really 'study' code to even get a feel of what it
does, let alone how it does it so I'll take your word for that. ;-(

I appreciate your time!

Np's ... especially as I have some projects in mind myself involving
some of the features you need. ;-)

Cheers, T i m
