Thanks Goran.

How can I get the minitraits source code so that I can attempt to 
fix it?

I understand that Traits is much more complete than MiniTraits, 
but I am in love with the whisker browser, and I suspected that 
using MiniTraits will interfere with it much less than Traits (I 
will check if this fear is justified)

Thanks for the help.

Take care,
Mike.

Receive and share.
