views2 block problem

Hi there,

I've created 5 views based on a clone of 1. And created block views for them.
All of them are working as they should but 1 of them gets a very strange id:
div#block-views-be85aed10cba19d2a43084695d9452b4
this should have been:
div#block-views-title-of-my-view

but it doesn't. I then deleted the view and created a new one based from the first one again. Same thing.
I deleted it again and created a total new view: same thing?
The weird thing is that it gives the same name as well:
div#block-views-be85aed10cba19d2a43084695d9452b4

You would expect it would be random.. apparently not..

I must say that I have invismail installed previous to tackling my views.. could this be the reason?

Thanx for listening/reading and hopefully for your help.
