Hi Adam,
              We are using version 4.5 .So I think this problem is there in only version 4.5.We are in the process of upgrading to version 5.

Also I did not get this problem when I typed text in the cuteeditor which I got from the link http://cutesoft.net/example/general.aspx.

So hope this problem would not occur in the version 5.Thanks for verifying and coming back immediately.

Thanks & Regards
Bomin
