JS error: adding hyperlinks with '%'

[steven@…]

1. select some text, and choose: add hyperlink.
   
2. Choose <other> and type '%PERS_4%' (my case) and click OK
   
3. now, select some other text, occuring later than the first text, and choose again: add hyperlink
   
4. Choose <other> and type '%PERS_4%' and click OK
   
5. Now there occurs a javascript error: line 108, char 2, "objet doesn't support this property or method", url: 'mydomain.com/admin/functions/editor/editor/fckdialog.html'. "Do you want to continue running scripts?"
   
6. Choosing either yes or no results in wrong hyperlink code in the html source.

This bug only applies to Internet Explorer 7, not Firefox IE6: not tested
