Problem: all internal links within a html field are suddenly all broken.
This seems to be fixed in CMS 7.5.
-Open some document (with IE8)
-Create some internal links to other documents
-Save this document
-Reopen and move cursor on an internal link. Add a character to this place.
-Save the document (or check htmlmode)
-All internal links are now broken (a / had been added to them, and the internal documents are no longer linked to the html field)
