Well ...
There are a couple of reasons for it - mostly "copy n' paste" out of "word" at all

As i view the html-output-source on some of your pages, i regonize a lot of messed "Microschrott-Word" Stuff, that
mess all up and produce __many__ problems at all.
Another question is, what wysiwyg-editor you are using and/or any droplets involved in the process at all?
Also - WB Version could be helpfull to know - and where you've got/downloaded the one you use is from.
At last - please feel free to form your question in english - as this one here is the english-part of the forum
Or ask one of the moderators to __move__ this one here to the german oneKind regards
