Progam hangs on one Item

[HippyCraig]

Im not sure what I am doing wrong, one Text time in my database keeps hanging the program. I created it fine but when I come back to make more edits the program goes non-responsive.

If I do an export of an item high in the tree and all sub items including the one thats cauasing issue, it exports fine to an RTF file. I can open and edit that file without issue, but when I copy the contents back in the same issue occurs.

I have created a new TEST.URD file, created a new text item and copied the copied in the same content as before, can you take a look and see whats causing this to hang?
