I am having a problem with users editing text.  They copy information from another source, and paste it

into the editor.  The information is placed in the database.  When they try to edit this information and press the

save button, the mouse arrow turns into a crosshair or crossarrow symbol, and the information is not saved.

This does not happen all of the time and only with certain tags.

Any information on this topic would be appreciated.

Thanks
