RichText item in Xpages through Internet Explorer

When pasting content from MS Office for example in RichText Editor in Xpage - first save is OK. After editing and after save content is automatically multiplied - 1-2-3 or more times and the worst is that it can multiply not the whole content but what it likes :-)This is reproducible only with IE, with mozzila it is OK.

Company policy is to use only IE. Anybody help?
