D'oh - you're totally right. You'll get a memory leak if you do it the way I suggested. Sorry about that. So could either use TObjArrays, or you'll have to copy the objects, just as you did. I believe Philippe already told you that you were not invoking the copy constructor properly.

That's right - seems like THtml is not picking up operators properly. There will be a new THtml version within the next two months which (hopefully) will do it right.
